Actually fix PPC64 64-bit GPR inline asm constraint matching
This is a follow-up to r187693, correcting that code to request the correct register class. The previous version, with the wrong register class, was not really correcting the constraints, but rather was removing them. Coincidentally, this fixed the failing test case in r187693, but obviously created other problems. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@188407 91177308-0d34-0410-b5e6-96231b3b80d8
