This patch fixes a bug where register writes performed by optimizable register moves were sometimes wrongly treated like partial register updates. Before this patch, llvm-mca wrongly predicted a 1.50 IPC for test reg-move-elimination-6.s (added by this patch). With this patch, llvm-mca correctly updates the register defintions in the PRF, and the IPC for that test is now correctly reported as 2. llvm-svn: 354271
