The dry-run of clang-tidy on the codebase with these enable were
well receive, and the codebase is "clean" (or almost) with respect
to these right now.
MLIR already exposes landingpads, the invokeop and the personality function on LLVM functions. With this intrinsic it should be possible to implement exception handling via the exception handling mechanisms provided by the Itanium ABI.

https://reviews.llvm.org/D109555 added support to APInt for this, so the special case to disable it is no longer valid. It is in fact legal to construct these programmatically today, and they print properly but do not parse.
Justification: zero bit integers arise naturally in various bit reduction optimization problems, and having them defined for MLIR reduces special casing.
I think there is a solid case for i0 and ui0 being supported. I'm less convinced about si0 and opted to just allow the parser to round-trip values that already verify. The counter argument is that the proper singular value for an si0 is -1. But the counter to this counter is that the sign bit is N-1, which does not exist for si0 and it is not unreasonable to consider this non-existent bit to be 0. Various sources consider it having the singular value "0" to be the least surprising.

These method currently takes a SmallVector<AffineExpr> & as an
argument to return the dims as AffineExpr. This creation of
AffineExpr objects is unnecessary.

Per the discussion in https://reviews.llvm.org/D116345 it makes sense
to move AtomicRMWOp out of the standard dialect. This was accentuated by the
need to add a fold op with a memref::cast. The only dialect
that would permit this is the memref dialect (keeping it in the standard dialect
or moving it to the arithmetic dialect would require those dialects to have a
dependency on the memref dialect, which breaks linking).
As the AtomicRMWKind enum is used throughout, this has been moved to Arith.

vector.transfer operations do not have rank-reducing semantics.
Bail on illegal rank-reduction: we need to check that the rank-reduced
dims are exactly the leading dims. I.e. the following is illegal:
```
%0 = vector.transfer_write %v, %t[0,0], %cst :
vector<2x4xf32>, tensor<2x4xf32>
%1 = tensor.insert_slice %0 into %tt[0,0,0][2,1,4][1,1,1] :
tensor<2x4xf32> into tensor<2x1x4xf32>
```
Cannot fold into:
```
%0 = vector.transfer_write %v, %t[0,0,0], %cst :
vector<2x4xf32>, tensor<2x1x4xf32>
```
For this, check the trailing `vectorRank` dims of the insert_slice result
tensor match the trailing dims of the inferred result tensor.

The semantics of the ops that implement the
`OffsetSizeAndStrideOpInterface` is that if the number of offsets,
sizes or strides are less than the rank of the source, then some
default values are filled along the trailing dimensions (0 for offset,
source dimension of sizes, and 1 for strides). This is confusing,
especially with rank-reducing semantics. Immediate issue here is that
the methods of `OffsetSizeAndStridesOpInterface` assumes that the
number of values is same as the source rank. This cause out-of-bounds
errors.
So simplifying the specification of `OffsetSizeAndStridesOpInterface`
to make it invalid to specify number of offsets/sizes/strides not
equal to the source rank.

Includes dependency fix that resulted in canonicalizer pass not linking in.
Linalg named ops lowering are moved to a separate pass. This allows TOSA
