Nemanja Ivanovic 7ebfc5f86b [Power9] Exploit D-Form VSX Scalar memory ops that target full VSX register set
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.
