For NVPTX, this fixes a crash where the emitImplicitDef implementation was expecting physical registers, while NVPTX uses virtual registers (with a couple of exceptions). Now, the implicit def comment will be emitted as a true PTX register name. Other targets can use this to customize the output of implicit def comments. Fixes PR17519 llvm-svn: 192444
