[AMDGPU] Add A16/G16 to InstCombine

[Flakebi]

Summary

When sampling from images with coordinates that only have 16 bit
accuracy, convert the image intrinsic call to use a16 or g16.
This does only happen if the target hardware supports it.

An alternative would be to always apply this combination, independent of
the target hardware and extend 16 bit arguments to 32 bit arguments
during legalization. To me, this sounds like an unnecessary roundtrip
that could prevent some further InstCombine optimizations.

No else after return. Also use match()?

Dead code

Don't need llvm::

The subtarget is already available in GCNTTI

Can you add a test making sure this preserves fast math flags? We should be able to mark these as nnan / ninf etc. and have it be preserved

[Flakebi]

Preserve fast-math flags and add test that ensures a16 combining is not done on gfx8.
