AMDGPU: Select DS insts without m0 initialization GFX9 stopped using m0 for most DS instructions. Select a different instruction without the use. I think this will be less error prone than trying to manually maintain m0 uses as needed. llvm-svn: 319270

[AMDGPU] Supported ds_read_b128 generation; Widened vector length for local address-space. Summary: Starting from GCN 2nd generation, ISA supports ds_read_b128 on top of ds_read_b64. This patch supports ds_read_b128 instruction pattern and generation of this instruction. In the vectorizer, this patch also widen the vector length so that vectorizer generates 128 bit loads for local address-space which gets translated to ds_read_b128. Since the performance benefit is not clear; compiler generates ds_read_b128 under -amdgpu-ds128.

AMDGPU: enable 128-bit for local addr space under an option Author: Samuel Pitoiset ds_read_b128 and ds_write_b128 have been recently enabled under the amdgpu-ds128 option because the performance benefit is unclear. Though, using 128-bit loads/stores for the local address space appears to introduce regressions in tessellation shaders. Not sure what is broken, but as ds_read_b128/ds_write_b128 are not enabled by default, just introduce a global option and enable 128-bit only if requested (until it's fixed/used correctly). v2: - fix regressions in merge-stores.ll and multiple_tails.ll Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=105464 llvm-svn: 329764
