Nemanja Ivanovic 766ca2c59e [PowerPC] Add missed VSX shuffles instead of Altivec ones ...

VSX introduced some permute instructions that are direct
replacements for Altivec ones except they can target all
the VSX registers. We have added code generation for most
of these but somehow missed the low/hi word merges (XXMRG[LH]W).
This caused some additional spills on some large
computationally intensive code.

This patch simply adds the missed patterns.
