Matthias Springer 83bf801f5f [mlir][NFC] Move SubTensorOp and SubTensorInsertOp to TensorDialect
The main goal of this commit is to remove the dependency of Standard dialect on the Tensor dialect.

* Rename ops: SubTensorOp --> ExtractTensorOp, SubTensorInsertOp --> InsertTensorOp
* Some helper functions are (already) duplicated between the Tensor dialect and the MemRef dialect. To keep this commit smaller, this will be cleaned up in a separate commit.
* Additional dialect dependencies: Shape --> Tensor, Tensor --> Standard
* Remove dialect dependencies: Standard --> Tensor
* Move canonicalization test cases to correct dialect (Tensor/MemRef).

Nicolas Vasilache e04533d38a [mlir][Linalg] Introduce a BufferizationAliasInfo (6/n)
This revision adds a BufferizationAliasInfo which maintains and updates information about which tensors will alias once bufferized, which bufferized tensors are equivalent to others and how to handle clobbers.

Bufferization greedily tries to bufferize inplace by:

1. first trying to bufferize SubTensorInsertOp inplace, in reverse order (these are deemed the most expensives).
2. then trying to bufferize all non SubTensorOp / SubTensorInsertOp, in reverse order.
3. lastly trying to bufferize all SubTensorOp in reverse order.

Reverse order is a heuristic that seems to work nicely because structured tensor codegen very often proceeds by:

1. take a subset of a tensor
2. compute on that subset
3. insert the result subset into the full tensor and yield a new tensor.

BufferizationAliasInfo + equivalence sets + clobber analysis allows bufferizing nested
subtensor/compute/subtensor_insert sequences inplace to a certain extent.
To fully realize inplace bufferization, additional container-containee analysis will be necessary and is left for a subsequent commit.

This revision adds support for passing a functor to SourceMgrDiagnosticHandler for filtering out FileLineColLocs when emitting a diagnostic. More specifically, this can be useful in situations where there may be large CallSiteLocs with locations that aren't necessarily important/useful for users.

For now the filtering support is limited to FileLineColLocs, but conceptually we could allow filtering for all locations types if a need arises in the future.

Uday Bondhugula 18c8c934d8 [MLIR] Introduce scf.execute_region op
Introduce the execute_region op that is able to hold a region which it
executes exactly once. The op encapsulates a CFG within itself while
isolating it from the surrounding control flow. Proposal discussed here:
https://llvm.discourse.group/t/introduce-std-inlined-call-op-proposal/282

execute_region enables one to inline a function without lowering out all
other higher level control flow constructs (affine.for/if, scf.for/if)
to the flat list of blocks / CFG form. It thus allows the benefit of
transforms on higher level control flow ops available in the presence of
the inlined calls. The inlined calls continue to benefit from
propagation of SSA values across their top boundary. Functions won’t
have to remain outlined until later than desired.  Abstractions like
affine execute_regions, lambdas with implicit captures could be lowered
to this without first lowering out structured loops/ifs or outlining.
But two potential early use cases are of: (1) an early inliner (which
can inline functions by introducing execute_region ops), (2) lowering of
an affine.execute_region, which cleanly maps to an scf.execute_region
when going from the affine dialect to the scf dialect.

Alex Zinenko a4f81b2054 [mlir] ODS: emit interface traits outside of the interface class
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.

Mehdi Amini c8a3f561eb Decouple registring passes from specifying argument/description
This patch changes the (not recommended) static registration API from:

 static PassRegistration<MyPass> reg("my-pass", "My Pass Description.");

to:

 static PassRegistration<MyPass> reg;

And the explicit registration from:

  void registerPass("my-pass", "My Pass Description.",
                    [] { return createMyPass(); });

To:

  void registerPass([] { return createMyPass(); });

It is expected that Pass implementations overrides the getArgument() method
instead. This will ensure that pipeline description can be printed and parsed
back.
