[llvm-branch-commits] AArch64: Emit PAuth ifuncs into the same comdat as the containing global. (PR #170965)

PAuth ifuncs contain a relocation pointing to the section they are
relocating (the place), so they need to be in the same comdat in order
to avoid relocations pointing to discarded sections.
