Jacques Pienaar 4b8632e174 [mlir] Expand operand adapter to take attributes
* Enables using with more variadic sized operands;
* Generate convenience accessors for attributes;
  - The accessor are named the same as their name in ODS and returns attribute
    type (not convenience type) and no derived attributes.

This is first step to changing adapter to support verifying argument
constraints before the op is even created. This does not change the name of
adaptor nor does it require it except for ops with variadic operands to keep this change smaller.

Considered creating separate adapter but decided against that given operands also require attributes in general (and definitely for verification of operands and attributes).

Jacques Pienaar 5eae715a31 [mlir] Add NamedAttrList
This is a wrapper around vector of NamedAttributes that keeps track of whether sorted and does some minimal effort to remain sorted (doing more, e.g., appending attributes in sorted order, could be done in follow up). It contains whether sorted and if a DictionaryAttr is queried, it caches the returned DictionaryAttr along with whether sorted.

Change MutableDictionaryAttr to always return a non-null Attribute even when empty (reserve null cases for errors). To this end change the getter to take a context as input so that the empty DictionaryAttr could be queried. Also create one instance of the empty dictionary attribute that could be reused without needing to lock context etc.

Update infer type op interface to use DictionaryAttr and use NamedAttrList to avoid incurring multiple conversion costs.

Fix bug in sorting helper function.

Lei Zhang 16027bbc3b [mlir][spirv] Serialize all operands together if possible
SPIR-V ops can mix operands and attributes in the definition. These
operands and attributes are serialized in the exact order of the definition
to match SPIR-V binary format requirements. It can cause excessive
generated code bloat because we are emitting code to handle each
operand/attribute separately. So here we probe first to check whether all
the operands are ahead of attributes. Then we can serialize all operands
together.

This removes ~1000 lines of code from the generated inc file.

Valentin Churavy 4f0f436749 [MLIR] Adjust libMLIR building to more closely follow libClang
- Exports MLIR targets to be used out-of-tree.
- mimicks `add_clang_library` and `add_flang_library`.
- Fixes libMLIR.so

After https://reviews.llvm.org/D77515 libMLIR.so was no longer containing
any object files. We originally had a cludge there that made it work with
the static initalizers and when switchting away from that to the way the
clang shlib does it, I noticed that MLIR doesn't create a `obj.{name}` target,
and doesn't export it's targets to `lib/cmake/mlir`.

This is due to MLIR using `add_llvm_library` under the hood, which adds
the target to `llvmexports`.

[MLIR] Fix libMLIR.so and LLVM_LINK_LLVM_DYLIB

Primarily, this patch moves all mlir references to LLVM libraries into
either LLVM_LINK_COMPONENTS or LINK_COMPONENTS.  This enables magic in
the llvm cmake files to automatically replace reference to LLVM components
with references to libLLVM.so when necessary.  Among other things, this
completes fixing libMLIR.so, which has been broken for some configurations
since D77515.

Unlike previously, the pattern is now that mlir libraries should almost
always use add_mlir_library.  Previously, some libraries still used
add_llvm_library.  However, this confuses the export of targets for use
out of tree because libraries specified with add_llvm_library are exported
by LLVM.  Instead users which don't need/can't be linked into libMLIR.so
can specify EXCLUDE_FROM_LIBMLIR

A common error mode is linking with LLVM libraries outside of LINK_COMPONENTS.
This almost always results in symbol confusion or multiply defined options
in LLVM when the same object file is included as a static library and
as part of libLLVM.so.  To catch these errors more directly, there's now
mlir_check_all_link_libraries.

To simplify usage of add_mlir_library, we assume that all mlir
libraries depend on LLVMSupport, so it's not necessary to separately specify
it.

tested with:
BUILD_SHARED_LIBS=on,
BUILD_SHARED_LIBS=off + LLVM_BUILD_LLVM_DYLIB,
BUILD_SHARED_LIBS=off + LLVM_BUILD_LLVM_DYLIB + LLVM_LINK_LLVM_DYLIB.

Alex Zinenko bb1d976feb [mlir][flang] use OpBuilder& instead of Builder* in <Op>::build methods
As we start defining more complex Ops, we increasingly see the need for
Ops-with-regions to be able to construct Ops within their regions in
their ::build methods. However, these methods only have access to
Builder, and not OpBuilder. Creating a local instance of OpBuilder
inside ::build and using it fails to trigger the operation creation
hooks in derived builders (e.g., ConversionPatternRewriter). In this
case, we risk breaking the logic of the derived builder. At the same
time, OpBuilder::create, which is by far the largest user of ::build
already passes "this" as the first argument, so an OpBuilder instance is
already available.

Update all ::build methods in all Ops in MLIR and Flang to take
"OpBuilder &" instead of "Builder *". Note the change from pointer and
to reference to comply with the common style in MLIR, this also ensures
all other users must change their ::build methods.

Tres Popp 2d2d696137 [MLIR] Propagate input side effect information
Summary:
Previously operations like std.load created methods for obtaining their
effects but did not inherit from the SideEffect interfaces when their
parameters were decorated with the information. The resulting situation
was that passes had no information on the SideEffects of std.load/store
and had to treat them more cautiously. This adds the inheritance
information when creating the methods.

As a side effect, many tests are modified, as they were using std.load
for testing and this oepration would be folded away as part of pattern
rewriting. Tests are modified to use store or to reutn the result of the
std.load.

River Riddle 4dfd1b5fcb [mlir] Optimize operand storage such that all operations can have resizable operand lists
This revision refactors the structure of the operand storage such that there is no additional memory cost for resizable operand lists until it is required. This is done by using two different internal representations for the operand storage:
* One using trailing operands
* One using a dynamically allocated std::vector<OpOperand>

This allows for removing the resizable operand list bit, and will free up APIs from needing to workaround non-resizable operand lists.

Stephen Neuendorffer 19fec004e2 [MLIR] Add note for file-line numbers in tablegen errors for assembly formats
Error messages for the custom assembly format are difficult to understand
because there are no line numbers.  This happens because the assembly format
is parsed as a standalone line, separate from it's parent file, with no useful
location information.  Fixing this properly probably requires quite a bit
of invasive plumbing through the SourceMgr, similar to how included files
are handled

This proposal is a less invasive short term solution.  When generating an
error message we generate an additional note which at least properly describes
the operation definition the error occured in, if not the actual line number
of the assemblyFormat definition.

A typical message is like:

error: type of operand #0, named 'operand', is not buildable and a buildable type cannot be inferred
  $operand type($result) attr-dict
  ^

River Riddle 9a277af2d4 [mlir][Pass] Add support for generating pass utilities via tablegen
This revision adds support for generating utilities for passes such as options/statistics/etc. that can be inferred from the tablegen definition. This removes additional boilerplate from the pass, and also makes it easier to remove the reliance on the pass registry to provide certain things(e.g. the pass argument).

River Riddle 8155e41ac6 [mlir][Pass] Add a tablegen backend for defining Pass information
This will greatly simplify a number of things related to passes:
* Enables generation of pass registration
* Enables generation of boiler plate pass utilities
* Enables generation of pass documentation

This revision focuses on adding the basic structure and adds support for generating the registration for passes in the Transforms/ directory. Future revisions will add more support and move more passes over.
