Convert this test to FileCheck, and improve it to check for the instructions it is trying to exclude instead of checking for register use (especially because grepping for r1 can be thrown off, for example, by a use of r12). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@195979 91177308-0d34-0410-b5e6-96231b3b80d8
