Sergei Grechanik b08ede4374 [MLIR] Fix MLIR vim syntax file
This commit fixes several things in the MLIR vim syntax file:
- Spell checking is now on by default only in comments.
- '#' now starts an identifier instead of starting an outline attribute
  declaration, which fixes coloring the rest of the line as a
  preprocessor directive when there is a '#' in the middle.
- '!' and '^' -prefixed identifiers are now colored as types
  and labels.

River Riddle 23aa5a7446 [mlir] Rename the Standard dialect to the Func dialect
The last remaining operations in the standard dialect all revolve around
FuncOp/function related constructs. This patch simply handles the initial
renaming (which by itself is already huge), but there are a large number
of cleanups unlocked/necessary afterwards:

* Removing a bunch of unnecessary dependencies on Func
* Cleaning up the From/ToStandard conversion passes
* Preparing for the move of FuncOp to the Func dialect

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.

Sean Silva 444822d77a Revert "Revert "[mlir] Start splitting the `tensor` dialect out of `std`.""
This reverts commit 0d48d265db.

This reapplies the following commit, with a fix for CAPI/ir.c:

[mlir] Start splitting the `tensor` dialect out of `std`.

This starts by moving `std.extract_element` to `tensor.extract` (this
mirrors the naming of `vector.extract`).

Curiously, `std.extract_element` supposedly works on vectors as well,
and this patch removes that functionality. I would tend to do that in
separate patch, but I couldn't find any downstream users relying on
this, and the fact that we have `vector.extract` made it seem safe
enough to lump in here.

This also sets up the `tensor` dialect as a dependency of the `std`
dialect, as some ops that currently live in `std` depend on
`tensor.extract` via their canonicalization patterns.

This reverts commit cab8dda90f.

I mistakenly thought that CAPI/ir.c failure was unrelated to this
change. Need to debug it.

Uday Bondhugula 47034c4bc5 Introduce prefetch op: affine -> std -> llvm intrinsic
Introduce affine.prefetch: op to prefetch using a multi-dimensional
subscript on a memref; similar to affine.load but has no effect on
semantics, but only on performance.

Provide lowering through std.prefetch, llvm.prefetch and map to llvm's
prefetch instrinsic. All attributes reflected through the lowering -
locality hint, rw, and instr/data cache.

  affine.prefetch %0[%i, %j + 5], false, 3, true : memref<400x400xi32>
