River Riddle 0c7890c844 [mlir] Convert NamedAttribute to be a class
NamedAttribute is currently represented as an std::pair, but this
creates an extremely clunky .first/.second API. This commit
converts it to a class, with better accessors (getName/getValue)
and also opens the door for more convenient API in the future.

Jacques Pienaar cfb72fd3a0 [mlir] Switch arith, llvm, std & shape dialects to accessors prefixed both form.
Following
https://llvm.discourse.group/t/psa-ods-generated-accessors-will-change-to-have-a-get-prefix-update-you-apis/4476,
this follows flipping these dialects to _Both prefixed form. This
changes the accessors to have a prefix. This was possibly mostly without
breaking breaking changes if the existing convenience methods were used.

(https://github.com/jpienaar/llvm-project/blob/main/clang-tools-extra/clang-tidy/misc/AddGetterCheck.cpp
was used to migrate the callers post flipping, using the output from
Operator.cpp)

Mogball a54f4eae0e [MLIR] Replace std ops with arith dialect ops
Precursor: https://reviews.llvm.org/D110200

Removed redundant ops from the standard dialect that were moved to the
`arith` or `math` dialects.

Renamed all instances of operations in the codebase and in tests.

Vladislav Vinogradov ec03bbe8a7 [mlir] Fix bug in partial dialect conversion
The discussion on forum:
https://llvm.discourse.group/t/bug-in-partial-dialect-conversion/4115

The `applyPartialConversion` didn't handle the operations, that were
marked as illegal inside dynamic legality callback.
Instead of reporting error, if such operation was not converted to legal set,
the method just added it to `unconvertedSet` in the same way as unknown operations.

This patch fixes that and handle dynamically illegal operations as well.

The patch includes 2 fixes for existing passes:

* `tensor-bufferize` - explicitly mark `std.return` as legal.
* `convert-parallel-loops-to-gpu` - ugly fix with marking visited operations
  to avoid recursive legality checks.

Chris Lattner dc4e913be9 [PatternMatch] Big mechanical rename OwningRewritePatternList -> RewritePatternSet and insert -> add. NFC
This doesn't change APIs, this just cleans up the many in-tree uses of these
names to use the new preferred names.  We'll keep the old names around for a
couple weeks to help transitions.

Alexander Belyaev a89035d750 Revert "[MLIR] Create memref dialect and move several dialect-specific ops from std."
This commit introduced a cyclic dependency:
Memref dialect depends on Standard because it used ConstantIndexOp.
Std depends on the MemRef dialect in its EDSC/Intrinsics.h

Stephan Herhut 5da2423bc0 [mlir][gpu] Only transform mapped parallel loops to GPU.
This exposes a hook to configure legality of operations such that only
`scf.parallel` operations that have mapping attributes are marked as

Allow propagating optional user defined attributes during SCF to GPU conversion. Gives opportunity to use user defined attributes in the further lowering. For example setting subgroup size, or other options for GPU dispatch. This does not break backward compatibility and does not require new attributes, just allow passing optional ones.

LoopsToGPU -> SCFToGPU, VectorToLoops -> VectorToSCF. Full file paths are
affected. Additionally, drop the 'Convert' prefix from filenames living under
lib/Conversion where applicable.

API names and CLI options for pass testing are also renamed when applicable. In
particular, LoopsToGPU contains several passes that apply to different kinds of
loops (`for` or `parallel`), for which the original names are preserved.
