computation was totally wrong, but somehow it didn't really show up with llc. I've added an assert that triggers on multiple existing test cases and updated one of them to show the correct value. There appear to still be more bugs lurking around insertps's mask. =/ However, note that this only really impacts the new vector shuffle lowering. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217289 91177308-0d34-0410-b5e6-96231b3b80d8
