Expand pseudo/macro BteqzT8SltuX16 . There is no test case because
at this time, llvm is generating a different but equivalent pattern that would lead to this instruction. I am trying to think of a way to get it to generate this. If I can't, I may just remove the pseudo. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@175419 91177308-0d34-0410-b5e6-96231b3b80d8
