eea72ccbf2 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.

The two-address instruction pass will convert these back to v_mad_f32
if necessary.
