  Log Message:
  -----------
  [ELF] Use tombstone values for discarded symbols in relocatable output

This extends D81784. Sections can be discarded when linking a
relocatable output. Before the patch, LLD did not update the content
of debug sections and only replaced the corresponding relocations with
R_*_NONE, which could break the debug information.
