[PATCH] [PATCH] Test case and FastISel fixes with FeatureVSX enabled

[Bill Schmidt]

Hi Bill,

This looks much better with the checking all in one place -- thanks for doing that!  I don't see any problems with the patch from my end -- will defer to Hal and Eric whether their concerns are all handled.

I see we will have an opportunity to improve code gen for mcm-12.ll.  Using the indexed-form VSX instruction allows use of more registers but means we need an extra addi in this sequence over just using lfd.  But that's for the future...
