43346ab61e AMDGPU: Fix recomputing dominator tree unnecessarily
SIFixSGPRCopies does not modify the CFG, but this was
being recomputed before running SIFoldOperands.

687b1fc846 AMDGPU/SI: Fold operands through REG_SEQUENCE instructions
Summary:
This helps mostly when we use add instructions for address calculations
that contain immediates.

ff149a4711 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.

if necessary.
