[PATCH] D104874: [AMDGPU] Add S_MOV_B64_IMM_PSEUDO for wide constants

[Stanislav Mekhanoshin via Phabricator via llvm-commits]

rampitec updated this revision to Diff 355353.
rampitec retitled this revision from "[AMDGPU] Add S_MOV_B64_IMM_PSEUDO for fp constants" to "[AMDGPU] Add S_MOV_B64_IMM_PSEUDO for wide constants".

Removed selection part, we will still select split wide constants.
Added pass to combine such assignments into the new pseudo after the coalescer and rename independent subregs.
This gives better results at a cost of compile time.
