- it only considers single level pointers, i.e., pointers of type T * regardless of whether T is again a pointer;

[mlir][scf] Fix builder of WhileOp with region builder arguments.
The overload of WhileOp::build with arguments for builder functions for
the regions of the op was broken: It did not compute correctly the types
(and locations) of the region arguments, which lead to failed assertions
when the result types were different from the operand types.
Specifically, it used the result types (and operand locations) for *both*
regions, instead of the operand types (and locations) for the 'before'
region and the result types (and loecations) for the 'after' region.

[debug-info] Followup to
e0374fb2f4, avoid changing codegen
As discussed on D140404, calling GetValueInMiddleOfBlock can force PHI
nodes to be created, but the patch was only supposed to fetch a Value if it
wasn't going to generate any PHIs. Fix this by using GetValueAtEndOfBlock
instead of the Middle variant, which was the original intention given the
check of HasValueForBlock.
We don't need to consider the "middle of block" scenario as we're only
dealing with blocks where there are no value definitions.

[LoopVectorize] Use DataLayout::getIndexType instead of i32 for non-constant GEP indices.
This is specifically relevant for loops that vectorize using a scalable VF,
where the code results in:
%vscale = call i32 llvm.vscale.i32()
%vf.part1 = mul i32 %vscale, 4
%gep = getelementptr ..., i32 %vf.part1
Which InstCombine then changes into:
%vscale = call i32 llvm.vscale.i32()
%vf.part1 = mul i32 %vscale, 4
%vf.part1.zext = sext i32 %vf.part1 to i64
%gep = getelementptr ..., i32 %vf.part1.zext
D143016 tried to remove these extends, but that only works when
the call to llvm.vscale.i32() has a single use. After doing any
kind of CSE on these calls the combine no longer kicks in.
It seems more sensible to ask DataLayout what type to use, rather
than relying on InstCombine to insert the extend and hoping it can
fold it away.
I've only changed this for indices that are not constant, because
I vaguely remember there was a reason for sticking with i32. It
would also mean patching up loads more tests.
