[PATCH] [PPC64LE] Remove unnecessary swaps from lane-insensitive vector computations

[Bill Schmidt]

Hm, pre-coffee comment.  I suspect you mean the last two tests where I removed the checks.  At this time they don't check anything to do with the xxpermdi.  Alternatively, I could leave the check in place and replace "count 12" with "count 0" or otherwise look at this.  Since those tests weren't designed to specifically check an optimization I initially chose to remove the check, but I could go either way.
