Kamau Bridgeman	cd83333fc8	[PowerPC] Fold redundant load immediates of zero and delete if possible ... This patch folds redundant load immediates into a zero for instructions which recognise this as the value zero and not the register. If the load immediate is no longer in use it is then deleted. This is already done in earlier passes but the ppc-mi-peephole allows for a more general implementation. Differential Revision: https://reviews.llvm.org/D69168	2020-05-12 13:15:06 -05:00
