[mlir][Vector] Add a folder for vector.broadcast

Fold the operation if the source is a scalar constant or splat constant.

Update transform-patterns-matmul-to-vector.mlir because the broadcast ops are folded in the conversion.

[AArch64][GlobalISel] Fix bug in fewVectorElts action while legalizing oversize G_FPTRUNC vectors.

For <8 x s32> = fptrunc <8 x s64> the fewerElementsVector action tries to break
down the source vector into the final source vectors of <2 x s64> using unmerge.
This fixes a crash due to using the wrong number of elements for the breakdown

Also add some legalizer tests for explicitly G_FPTRUNC which we didn't have.

Commit 7f7993e0daf459c308747f034e3fbd73889c7ab3 by
[ARM] Expand distributing increments to also handle existing pre/post inc instructions.

This extends the distributing postinc code in load/store optimizer to
also handle the case where there is an existing pre/post inc instruction,
where subsequent instructions can be modified to use the adjusted
offset from the increment. This can save us having to keep the old
register live past the increment instruction.

[SyntaxTree][Synthesis] Fix allocation in `createTree` for more general use

Prior to this change `createTree` could not create arbitrary syntax
trees. Now it dispatches to the constructor of the concrete syntax tree
according to the `NodeKind` passed as argument. This allows reuse inside
the Synthesis API.  # Please enter the commit message for your changes.

[Sema] Introduce BuiltinAttr, per-declaration builtin-ness

Instead of relying on whether a certain identifier is a builtin, introduce BuiltinAttr to specify a declaration as having builtin semantics.

This fixes incompatible redeclarations of builtins, as reverting the identifier as being builtin due to one incompatible redeclaration would have broken rest of the builtin calls.
Mostly-compatible redeclarations of builtins also no longer have builtin semantics. They don't call the builtin nor inherit their attributes.
A long-standing FIXME regarding builtins inside a namespace enclosed in extern "C" not being recognized is also addressed.

Due to the more correct handling attributes for builtin functions are added in more places, resulting in more useful warnings.
Tests are updated to reflect that.

Intrinsics without an inline definition in intrin.h had `inline` and `static` removed as they had no effect and caused them to no longer be recognized as builtins otherwise.

A pthread_create() related test is XFAIL-ed, as it relied on it being recognized as a builtin based on its name.
The builtin declaration syntax is too restrictive and doesn't allow custom structs, function pointers, etc.
It seems to be the only case and fixing this would require reworking the current builtin syntax, so this seems acceptable.

Fixes PR45410.

[MLIR][Affine] Add parametric tile size support for affine.for tiling

Add support to tile affine.for ops with parametric sizes (i.e., SSA
values). Currently supports hyper-rectangular loop nests with constant
lower bounds only. Move methods

  - moveLoopBody(*)
  - getTileableBands(*)
  - checkTilingLegality(*)
  - tilePerfectlyNested(*)
  - constructTiledIndexSetHyperRect(*)

to allow reuse with constant tile size API. Add a test pass -test-affine
-parametric-tile to test parametric tiling.
