SIInstrInfo::FoldImmediate tried to delete move-immediate instructions after folding them into their only use. This did not work because it was checking hasOneNonDBGUse after doing the fold, at which point there should be no uses. This seems to have no effect on codegen, it just means less stuff for DCE to clean up later. Differential Revision: https://reviews.llvm.org/D120815
