This allows the indexing sugar to just work naturally with other type of load and store ops than the affine ones we currently have.
This is needed for the EuroLLVM tutorial.

This is useful when developing one or multiple dialects in a private context without having to register them with MLIR Core.

This eliminate ConstOpPointer (but keeps OpPointer for now) by making OpPointer
implicitly launder const in a const incorrect way. It will eventually go away
entirely, this is a progressive step towards the new const model.

Previously we emit both op declaration and definition into one file and include it
in *Ops.h. That pulls in lots of implementation details in the header file and we
cannot hide symbols local to implementation. This CL splits them to provide a cleaner
interface.
The way how we define custom builders in TableGen is changed accordingly because now
we need to distinguish signatures and implementation logic. Some custom builders with
complicated logic now can be moved to be implemented in .cpp entirely.

This CL fixes an issue where cloned loop induction variables were not properly
propagated and beefs up the corresponding test.

Avoids including function in C++ side that resulted in OSS C++ errors:
include/mlir-c/Core.h:228:16: error: functions that differ only in their
return type cannot be overloaded
edsc_indexed_t index(edsc_indexed_t indexed, edsc_expr_list_t indices);
~~~~~~~~~~~~~~ ^
/usr/include/string.h:484:14: note: previous declaration is here
extern char *index (const char *__s, int __c)
And as these are going away soon, just removing the function requires the least changes.

Previously Value was a pair of name & Type, but for operands/result a TypeConstraint rather then a Type is specified. Update C++ side to match declarative side.

This CL introduces a ValueArrayHandle helper to manage the implicit conversion
of ArrayRef<ValueHandle> -> ArrayRef<Value*> by converting first to ValueArrayHandle.
Without this, boilerplate operations that take ArrayRef<Value*> cannot be removed easily.
This all seems to boil down to decoupling Value from Type.
Alternative solutions exist (e.g. MLIR using Value by value everywhere) but they would be very intrusive. This seems to be the lowest impedance change.
Intrinsics are also lowercased by popular demand.

This CL removes the dependency of LowerVectorTransfers on the AST version of EDSCs which will be retired.
This exhibited a pretty fundamental staging difference in AST-based vs declarative based emission.
Since the delayed creation with an AST was staged, the loop order came into existence after the clipping expressions were computed.
This now changes as the loops first need to be created declaratively in fixed order and then the clipping expressions are created.
Also, due to lack of staging, coalescing cannot be done on the fly anymore and
needs to be done either as a pre-pass (current implementation) or as a local transformation on the generated IR (future work).
Tests are updated accordingly.

In particular, expose comparison operators as Python operator overloads on
ValueHandles. The comparison currently emits signed integer comparisons only,
which is compatible with the behavior of emitter-based EDSC interface. This is
sub-optimal and must be reconsidered in the future. Note that comparison
operators are not overloaded in the C++ declarative builder API precisely
because this avoids the premature decision on the signedness of comparisons.
Implement the declarative construction of boolean expressions using
ValueHandles by overloading the boolean operators in the `op` namespace to
differentiate between `operator!` for nullity check and for boolean negation.
The operands must be of i1 type. Also expose boolean operations as Python
operator overloads on ValueHandles.

In particular, expose `cond_br`, `select` and `call` operations with syntax
similar to that of the previous emitter-based EDSC interface. These are
provided for backwards-compatibility. Ideally, we want them to be
Table-generated from the Op definitions when those definitions are declarative.
Additionally, expose the ability to construct any op given its canonical name,
which also exercises the construction of unregistered ops.

Expose edsc::IndexedValue using a syntax smilar to that of edsc::Indexed to
ensure backwards-compatibility. It remains possible to write array-indexed
loads and stores as
C.store([i, j], A.load([i, k]) * B.load([k, j]))
after taking a "view" of some value handle using IndexedValue as
A = IndexedValue(originalValueHandle)
provided that all indices are also value handles.

In the original implementation, constants could be bound to EDSC expressions in
the binder, independently from other MLIR Values. A rework of EDSC including
early typing provided the functionality to use MLIR's `constant` operation to
define typed constants instead of binding them separately, but only used it for
index types. The new declarative builder implementation followed by providing
a call for building `constant` operations of index types but nothing more.
Expose similar builders for integers, floats and functions to match the what
binders allow one to use.

Provide a function `arg` that returns the function argument as a value handle,
similar to block arguments. This makes function context managers in Python
similar to block context managers, which is more consistent given that the
function context manager sets the insertion point to the first block of the
function and that arguments of that block are those of the function. This
prepares the removal of PythonMLIREmitter class and its bind_function_arguments
helper.
Additionally, provide a helper method in PythonMLIRModule to define a function
and immediately create a context for it. Update the tests that are already
using context managers to use the function context manager instead of creating
the function manually.
