The PC Relative code now allows for calls that are marked with the relocation R_PPC64_REL24_NOTOC. This indicates that the caller does not have a valid TOC pointer in R2 <https://reviews.llvm.org/source/clang-tools-extra/> and does not require R2 <https://reviews.llvm.org/source/clang-tools-extra/> to be restored after the call. This patch is added to support local calls to callees that require a TOC
