[CodeGen][SplitKit] Fix a crash in addDeadDef (#197014)
This commit fixes https://github.com/llvm/llvm-project/issues/178867.
The problem was that we were trying to materialize a lanemask that does
not existing in the parent live-interval and were crashing.
This happened because we were using the original live-interval to
materialize the live subranges (original is the ancestor of the parent
and may cover some lanes in the lanemasks that are not covered by the
parent live-interval).
The crash was reported by a downstream user and they were not able to
capture the issue with an upstream target. The issue appears because of
the refining of the subranges. We are creating values out of thin air
but they may cover more lanes than the parent because we infer them from
the original live-range.
The fix consists in taking the lanes covered by the parent, not the
original value, when creating the live-interval for the children.

[mlir][vector] Drop leading unit dims in memref op folding (#197278)
Make the IndexedAccessOpInterface implementations for vector dialect
operations a bit smarter by letting them drop redundant unit dimensions
and shape_cast operations back. This allows folding in, for example, an
expand_shape of a 1-D memref to a load of a `vector<1x1x8xf32>` by
turning it into a load of a `vector<8xf32>` instead. This functionality
is somewhat reduntant with dropleadunitdims, but is included for
completeness and to better match the interface contract of
IndexedAccessOpInterface.
While we're here, fix a bug in the verifier of
vector.expandshape/collapsestore - as near as I can tell, they were
meant to check for the mask being the
same shape is the input vector, but they just checked the first
dimension.
