Lei Zhang e5c85a5a4f [mlir][spirv] Support querying type extension/capability requirements
Previously we only consider the version/capability/extension requirements
on ops themselves. Some types in SPIR-V also require special extensions
or capabilities to be used. For example, non-32-bit integers/floats
will require different capabilities and/or extensions depending on
where they are used because it may mean special hardware abilities.

This commit adds query methods to SPIR-V type class hierarchy to support
querying extensions and capabilities. We don't go through ODS for
auto-generating such information given that we don't have them in
SPIR-V machine readable grammar and there are just a few types.

Lei Zhang 2ae5e472e6 [mlir][spirv] Use SmallVector<ArrayRef> for availability queries
Previously extensions and capabilities requirements are returned as
SmallVector<SmallVector>. It's an anti-pattern; this commit improves
a bit by returning as SmallVector<ArrayRef>. This is possible because
the internal sequence is always known statically (from the spec)
so that we can use a static constant array for it and get an ArrayRef.

Lei Zhang 3148f10b17 [mlir][spirv] Use spv.vce in spv.module and wire up (de)serialization
This commits changes the definition of spv.module to use the #spv.vce
attribute for specifying (version, capabilities, extensions) triple
so that we can have better API and custom assembly form. Since now
we have proper modelling of the triple, (de)serialization is wired up
to use them.

With the new UpdateVCEPass, we don't need to manually specify the
required extensions and capabilities anymore when creating a spv.module.
One just need to call UpdateVCEPass before serialization to get the
needed version/extensions/capabilities.

Lei Zhang 9414db1090 [mlir][spirv] Add a pass to deduce version/extension/capability
Creates an operation pass that deduces and attaches the minimal version/
capabilities/extensions requirements for spv.module ops.

For each spv.module op, this pass requires a `spv.target_env` attribute on
it or an enclosing module-like op to drive the deduction. The reason is
that an op can be enabled by multiple extensions/capabilities. So we need
to know which one to pick. `spv.target_env` gives the hard limit as for
what the target environment can support; this pass deduces what are
actually needed for a specific spv.module op.

We also need the (version, capabilities, extensions) triple on the

Nick Desaulniers 246398ece7 [clang][Parse] properly parse asm-qualifiers, asm inline
Summary:
The parsing of GNU C extended asm statements was a little brittle and
had a few issues:
- It was using Parse::ParseTypeQualifierListOpt to parse the `volatile`
  qualifier.  That parser is really meant for TypeQualifiers; an asm
  statement doesn't really have a type qualifier. This is still maybe
  nice to have, but not necessary. We now can check for the `volatile`
  token by properly expanding the grammer, rather than abusing
  Parse::ParseTypeQualifierListOpt.
- The parsing of `goto` was position dependent, so `asm goto volatile`
  wouldn't parse. The qualifiers should be position independent to one
  another. Now they are.
- We would warn on duplicate `volatile`, but the parse error for
  duplicate `goto` was a generic parse error and wasn't clear.
- We need to add support for the recent GNU C extension `asm inline`.
  Adding support to the parser with the above issues highlighted the
  need for this refactoring.

River Riddle 0ddba0bd59 [mlir][SideEffects] Replace HasNoSideEffect with the memory effect interfaces.
HasNoSideEffect can now be implemented using the MemoryEffectInterface, removing the need to check multiple things for the same information. This also removes an easy foot-gun for users as 'Operation::hasNoSideEffect' would ignore operations that dynamically, or recursively, have no side effects. This also leads to an immediate improvement in some of the existing users, such as DCE, now that they have access to more information.

River Riddle 907403f342 [mlir] Add a new `ConstantLike` trait to better identify operations that represent a "constant".
The current mechanism for identifying is a bit hacky and extremely adhoc, i.e. we explicit check 1-result, 0-operand, no side-effect, and always foldable and then assume that this is a constant. Adding a trait adds structure to this, and makes checking for a constant much more efficient as we can guarantee that all of these things have already been verified.

aartbik 078776a679 [mlir] [VectorOps] Progressively lower vector.outerproduct to LLVM
Summary:
This replaces the direct lowering of vector.outerproduct to LLVM with progressive lowering into elementary vectors ops to avoid having the similar lowering logic at several places.

NOTE1: with the new progressive rule, the lowered llvm is slightly more elaborate than with the direct lowering, but the generated assembly is just as optimized; still if we want to stay closer to the original, we should add a "broadcast on extract" to shuffle rewrite (rather than special cases all the lowering steps)

NOTE2: the original outerproduct lowering code should now be removed but some linalg test work directly on vector and contain some dead code, so this requires another CL

This fixes the issue by setting the CXX_STANDARD property of the benchmark

The CMake documentation is not clear whether this will use the C++1z
fallback for older compilers. So this may break the benchmarks if somebody
uses the benchmarks with pre C++17 compilers with the C++1z fallback.
