Use "STC;MVC" for memsets that are too big for two STCs or MV...Is yet small enough for a single MVC. As with memcpy, I'm leaving longer cases till later. The number of tests might seem excessive, but f33 & f34 from memset-04.ll failed the first cut because I'd not added the "?:" on the calculation of Size1. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@185918 91177308-0d34-0410-b5e6-96231b3b80d8
