ODS currently emits the interface trait class as a nested class inside the
interface class. As an unintended consequence, the default implementations of
interface methods have implicit access to static fields of the interface class,
e.g. those declared in `extraClassDeclaration`, including private methods (!),
or in the parent class. This may break the use of default implementations for
external models, which are not defined in the interface class, and generally
complexifies the abstraction.
Emit intraface traits outside of the interface class itself to avoid accidental
implicit visibility. Public static fields can still be accessed via explicit
qualification with a class name, e.g., `MyOpInterface::staticMethod()` instead
of `staticMethod`.
Update the documentation to clarify the role of `extraClassDeclaration` in
interfaces.

Interface patterns are unique in that they get added to every operation that also implements that interface, given that they aren't tied to individual operations. When the same interface pattern gets added to multiple operations (such as the current behavior with Linalg), an reference to each of these patterns is added to every op (meaning that an operation will now have N references to effectively the same pattern).

This changes the outer verification loop to not recurse into

This speeds up firtool in CIRCT from ~40s to 31s on a large

Up to now all structured op operands are assumed to be shaped. The patch relaxes this assumption and allows scalar input operands. In contrast to shaped operands scalar operands are not indexed and directly forwarded to the body of the operation. As all other operands, scalar operands are associated to an indexing map that in case of a scalar or a 0D-operand has an empty range.
We will use scalar operands as a replacement for the capture mechanism. In contrast to captures, the approach ensures we can generate the function signature from the operand list and it prevents outdated capture values in case a transformation updates only the capture operand but not the hidden body of a named operation.
Removing captures and updating existing operations such as linalg.fill is left for a later patch.

Differential Revision: https://reviews.llvm.org/D104009
## Introduction
This proposal describes the new op to be added to the `std` (and later moved `memref`)
dialect called `alloca_scope`.
## Motivation
Alloca operations are easy to misuse, especially if one relies on it while doing
rewriting/conversion passes. For example let's consider a simple example of two
independent dialects, one defines an op that wants to allocate on-stack and
another defines a construct that corresponds to some form of looping:
```
dialect1.looping_op {
%x = dialect2.stack_allocating_op
}
```
Since the dialects might not know about each other they are going to define a
lowering to std/scf/etc independently:
```
scf.for … {
%x_temp = std.alloca …
… // do some domain-specific work using %x_temp buffer
… // and store the result into %result
%x = %result
}
```
Later on the scf and `std.alloca` is going to be lowered to llvm using a
combination of `llvm.alloca` and unstructured control flow.
At this point the use of `%x_temp` is bound to either be either optimized by
llvm (for example using mem2reg) or in the worst case: perform an independent
stack allocation on each iteration of the loop. While the llvm optimizations are
likely to succeed they are not guaranteed to do so, and they provide
opportunities for surprising issues with unexpected use of stack size.
## Proposal
We propose a new operation that defines a finer-grain allocation scope for the
alloca-allocated memory called `alloca_scope`:
```
alloca_scope {
%x_temp = alloca …
...
}
```
Here the lifetime of `%x_temp` is going to be bound to the narrow annotated
region within `alloca_scope`. Moreover, one can also return values out of the
alloca_scope with an accompanying `alloca_scope.return` op (that behaves
similarly to `scf.yield`):
```
%result = alloca_scope {
%x_temp = alloca …
…
alloca_scope.return %myvalue
}
```
Under the hood the `alloca_scope` is going to lowered to a combination of
`llvm.intr.stacksave` and `llvm.intr.strackrestore` that are going to be invoked
automatically as control-flow enters and leaves the body of the `alloca_scope`.
The key value of the new op is to allow deterministic guaranteed stack use
through an explicit annotation in the code which is finer-grain than the
function-level scope of `AutomaticAllocationScope` interface. `alloca_scope`
can be inserted at arbitrary locations and doesn’t require non-trivial
transformations such as outlining.
## Which dialect
Before memref dialect is split, `alloca_scope` can temporarily reside in `std`
dialect, and later on be moved to `memref` together with the rest of
memory-related operations.
## Implementation
An implementation of the op is available [here](https://reviews.llvm.org/D97768).
Original commits:
* Add initial scaffolding for alloca_scope op
* Add alloca_scope.return op
* Add no region arguments and variadic results
* Add op descriptions
* Add failing test case
* Add another failing test

One of the key algorithms used in the "mlir::verify(op)" method is the
dominance checker, which ensures that operand values properly dominate
the operations that use them.
The MLIR dominance implementation has a number of algorithmic problems,
and is not really set up in general to answer dense queries: it's constant
factors are really slow with multiple map lookups and scans, even in the
easy cases. Furthermore, when calling mlir::verify(module) or some other
high level operation, it makes sense to parallelize the dominator
verification of all the functions within the module.
This patch has a few changes to enact this:
1) It splits dominance checking into "IsolatedFromAbove" units. Instead
of building a monolithic DominanceInfo for everything in a module,
for example, it checks dominance for the module to all the functions
within it (noop, since there are no operands at this level) then each
function gets their own DominanceInfo for each of their scope.
2) It adds the ability for mlir::DominanceInfo (and post dom) to be
constrained to an IsolatedFromAbove region. There is no reason to
recurse into IsolatedFromAbove regions since use/def relationships
can't span this region anyway. This is already checked by the time
the verifier gets here.
3) It avoids querying DominanceInfo for trivial checks (e.g. intra Block
references) to eliminate constant factor issues).
4) It switches to lazily constructing DominanceInfo because the trivial
check case handles the vast majority of the cases and avoids
constructing DominanceInfo entirely in some cases (e.g. at the module
level or for many Regions's that contain a single Block).
5) It parallelizes analysis of collections IsolatedFromAbove operations,
e.g. each of the functions within a Module.
All together this is more than a 10% speedup on `firtool` in circt on a
large design when run in -verify-each mode (our default) since the verifier
is invoked after each pass.
Still todo is to parallelize the main verifier pass. I decided to split
this out to its own thing since this patch is already large-ish.

The `clang/.clang-tidy` change is a no-op, disabling an option that was never enabled.
The compiler-rt and flang changes are no-op reorderings of the same flags.
(side note, the .clang-tidy file in parallel-libs is broken and crashes
clang-tidy because it uses "lowerCase" as the style instead of "lower_case" -
so I'll deal with that separately)

This patch simplifies the implementation of Sequence and makes it compatible with llvm::reverse.
It exposes the reverse iterators through rbegin/rend which prevents a dangling reference in std::reverse_iterator::operator++().

* Mark the following methods const:
* `ArrayAttr::getAsRange`
* `ArrayAttr::getAsValueRange`
* `DictionaryAttr::getAs`
* Make `DictionarAttr::getAs` generic over the name class, such that
`Identifier` and `StringRef` arguments get forwarded to the underlying
call to `get`. (Made generic to avoid introducing a dependency on
`include/mlir/IR/Identifier.h` as per the diff discussion.)

Now that memref supports arbitrary element types, add support for memref of
memref and make sure it is properly converted to the LLVM dialect. The type
support itself avoids adding the interface to the memref type itself similarly
to other built-in types. This allows the shape, and therefore byte size, of the
memref descriptor to remain a lowering aspect that is easier to customize and
evolve as opposed to sanctifying it in the data layout specification for the
memref type itself.
Factor out the code previously in a testing pass to live in a dedicated data
layout analysis and use that analysis in the conversion to compute the
allocation size for memref of memref. Other conversions will be ported
separately.

Historically, MemRef only supported a restricted list of element types that
were known to be storable in memory. This is unnecessarily restrictive given
the open nature of MLIR's type system. Allow types to opt into being used as
MemRef elements by implementing a type interface. For now, the interface is
merely a declaration with no methods. Later, methods to query, e.g., the type
size or whether a type can alias elements of another type may be added.
Harden the "standard"-to-LLVM conversion against memrefs with non-builtin
types.

Some places in the alloc-like op conversion use the converted index type
whereas other places use the pointer-sized integer type, which may not be the
same. Consistently use the converted index type, similarly to other address
calculations.

These `arm_sve.cmp` functions are needed to generate scalable vector
masks as long as scalable vectors are not part of the standard types.
Once in standard, these can be removed and `std.cmp` can be used

This patch convert the if condition on standalone data operation such as acc.update,
acc.enter_data and acc.exit_data to a scf.if with the operation in the if region.
It removes the operation when the if condition is constant and false. It removes the
the condition if it is contant and true.
Conversion to scf.if is done in order to use the translation to LLVM IR dialect out of the box.
Not sure this is the best approach or we should perform this during the translation from OpenACC
to LLVM IR dialect. Any thoughts welcome.

This is a followup to D103422. The DenseMapInfo implementations for
ArrayRef and StringRef are moved into the ArrayRef.h and StringRef.h

This required adding a few additional includes, as many files were
