6fe7acaaf8 AMDGPU/SI: Add debugging subtarget feature for DS offsets 
We don't have a good way to detect most situations where
DS offsets are usable on SI, so add an option to force using
them even if unsafe for debugging performance problems.

1a5b04c725 RegisterCoalescer: Cleanup empty subranges after shrinkToUses() 
A call to removeEmptySubranges() is necessary after every operation that
potentially removes all segments from a subregister range; this case in
the register coalescer was missing.

0d1bd457c6 AMDGPU/SI: Emit amd_kernel_code_t in EmitFunctionBodyStart() 
Summary:
This way the function symbol points to the start of amd_kernel_code_t
rather than the start of the function.

e874345be4 AMDGPU: really don't commute REV opcodes if the target variant doesn't exist 
If pseudoToMCOpcode failed, we would return the original opcode, so operands
would be swapped, but the instruction would remain the same.
It resulted in LSHLREV a, b ---> LSHLREV b, a.

This fixes Glamor text rendering and
piglit/arb_sample_shading-builtin-gl-sample-mask on VI.

This is a candidate for stable branches.

5202cab841 Revert "Revert "Fix merges of non-zero vector stores"" 
Reapply r239539. Don't assume the collected number of
stores is the same vector size. Just take the first N
stores to fill the vector.
