If there are objections to adding this, I'm happy to remove it. The reason I added it is that I find it frustrating that I can't specify FileCheck patterns that ensure that a VSX instruction's result is the correct operand of a VMX instruction and vice-versa.

I could also wrap this in an
  #ifndef _NDEBUG
block, but then we would have to ensure that test cases that use it somehow require LLVM Asserts.
