	R11's status is the same under both the PPC64 ELF V1 and V2 ABIs: it is reserved for use as an "environment pointer" for compilation models that require such a thing. We don't, we also don't need a second scratch register, and because we support only "local" patchpoint call targets, we might as well let R11 be used for anyregcc patchpoints. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@226369 91177308-0d34-0410-b5e6-96231b3b80d8
