> Can you please describe why this change is desired?

When I work on https://reviews.llvm.org/D107886, I observe there are duplicated codes in PPCFrameLowering and PPCRegisterInfo to materialize immediates. I implemented a routine to get it work https://reviews.llvm.org/D107886#C2797592NL3233. I realized it also applies to virtual registers in non-SSA form. Before applying the routine mentioned above, I have to refactor this part of code a bit.
