This patch corresponds to review: The newly added VSX D-Form (register + offset) memory ops target the upper half of the VSX register set. The existing ones target the lower half. In order to unify these and have the ability to target all the VSX registers using D-Form operations, this patch defines Pseudo-ops for the loads/stores which are expanded post-RA. The expansion then choses the correct opcode based on the register that was allocated for the operation. llvm-svn: 283212
