The goal of this patch is exclude AArch64 mapping symbols ($x and $d) for symtab symbolization as it was done for ARM since D95916 <https://reviews.llvm.org/D95916> to bring the bots back to green state.

This is implemented by setting  `SF_FormatSpecific` such that llvm-symbolizer will ignore them, and use this flag to re-implement llvm-nm `--special-syms` option, by doing so it will work on AArch64 and ARM (it wasn't working on the later one since SF_FormatSpecific` symbols were ignored in llvm-nm).
