62d946e133 GlobalISel: Merge some AMDGPU ABI lowering code to generic code
AMDGPU currently has a lot of pre-processing code to pre-split
argument types into 32-bit pieces before passing it to the generic
code in handleAssignments. This is a bit sloppy and also requires some
overly fancy iterator work when building the calls. It's better if all
argument marshalling code is handled directly in
handleAssignments. This handles more situations like decomposing large
element vectors into sub-element sized pieces.

This should mostly be NFC, but does change the generated code by
shifting where the initial argument packing instructions are placed. I
think this is nicer looking, since it now emits the packing code
directly after the relevant copies, rather than after the copies for
the remaining arguments.

This doubles down on gfx6/gfx7 using the gfx8+ ABI for 16-bit
types. This is ultimately the better option, but incompatible with the
DAG. Fixing this requires more work, especially for f16.

8214982b50 [AMDGPU] Implement mir parseCustomPseudoSourceValue
Allow parsing generated mir with custom pseudo source value tokens.
Also rename pseudo source values to have more meaningful names.

Relands ba7dcd8542ab, which had memory leaks.

d07f9e7309 [AMDGPU] Allow struct.buffer.*.format intrinsics to accept i32
Summary:
In the same manner as struct.buffer.load / struct.buffer.store,
allow struct.buffer.load.format / struct.buffer.store.format to
return / accept any type.  This simplifies front-end code gen.
