just to give some context about `__llvm_profile_keep` (no need to take action):
the `__llvm_profile_keep` references a bunch of stub data variables that are
necessary to allow the linker to define the `__stop___llvm_prf_vnds` and other
start/stop symbols, which are live because they are referenced by parts of the
runtime that compute the filename. The start/stop symbols are weak
declarations, but on AIX an undefined WEAK is an error (just like a regular
undefined), so we need those stub data variables and stop the linker from
GC'ing them.
