[PATCH] D103717: [InstrProfiling][ELF] Make __profd_ private if the function does not use value profiling

Thanks for review:) I feel that I understand value profiling better now.

I have a plan to use label differences (i.e. PC-relative relocations on ELF) (D104556 <https://reviews.llvm.org/D104556>) to save `sizeof(Elf64_Rela) * |__profd_| = 24 * instrumented_functions` bytes.
