7a6a7f2409 AMDGPU: Fix recomputing dominator tree unnecessarily
SIFixSGPRCopies does not modify the CFG, but this was
being recomputed before running SIFoldOperands.

117c014fc5 AMDGPU/SI: Fix creating v_mov_b32s without exec uses
This will be caught by existing tests with a
verifier check to be added in a future commit.

6680fc3579 AMDGPU/SI: Fold operands through REG_SEQUENCE instructions
Summary:
This helps mostly when we use add instructions for address calculations
that contain immediates.

127a3d74f1 AMDGPU/SI: Fix some invaild assumptions when folding 64-bit immediates
Summary:
We were assuming tha if the use operand had a sub-register that
the immediate was 64-bits, but this was breaking the case of
folding a 64-bit immediate into another 64-bit instruction.

f5be357d37 AMDGPU/SI: Select mad patterns to v_mac_f32
The two-address instruction pass will convert these back to v_mad_f32
if necessary.
