AMDGPU/GlobalISel: Legalize odd sized loads with widening

[arsenm]

Summary

Custom lower and widen odd sized loads up to the alignment. The
default set of legalization actions doesn't have a way to represent
this. This fixes naturally aligned <3 x s8> and <3 x s16> loads.

This also starts moving towards eliminating the buggy and
overcomplicated legalization rules for narrowing. All the memory size
changes should be done in the lower or custom action, not NarrowScalar
/ FewerElements. These currently have redundant and ambiguous code
with the lower action.

Looks OK to me but I don't understand all the details. @mbrkusanin could you take a look at this one?

llvm/lib/Target/AMDGPU/AMDGPULegalizerInfo.cpp

2303–2308

Ty.changeElementSize(PowerOf2Ceil(Ty.getScalarSizeInBits()))?

[arsenm]

llvm/lib/Target/AMDGPU/AMDGPULegalizerInfo.cpp

2303–2308

I think that should only be used to handle cases that could be a vector or not, but it’s known scalar here so doesn’t save code

llvm/lib/Target/AMDGPU/AMDGPULegalizerInfo.cpp

2303–2308

I meant as a replacement for all of lines 2303-2308, but now I see that in the vector case you're increasing the number of elements, not the size of each element.

Could use Ty.changeNumElements(PowerOf2Ceil(Ty.getNumElements())) in the vector case.

[arsenm]

Use changeNumElements

[foad]

Looks good, just a couple of questions inline.

Is there any good reason why this widens to s64 and then s128, insteading of doing it in one step?

Where is the tbaa preserved in the GMIR for these tests? I don't see it.

Ouch that's a big expansion! I hope most of it can be optimized away one day.

I think this makes more sense for zext, where the high 64-bits can be done with a single s_mov_b64, and anyext just inherits from this logic

It's not, this is for the follow on commit to fix it

There are a lot of legalization messes to deal with
