  [AMDGPU] Fix adding modifiers when creating v_cmpx instructions.

Revision https://reviews.llvm.org/D122332 added a pattern transformation
where v_cmpx instructions are introduced. However, the modifiers are
not correctly inherited from the original operands. The patch
adds the source modifiers, if they are exist, or sets them to 0.
