  Changed paths:
    M lld/ELF/SyntheticSections.cpp
    R lld/test/ELF/debug-gnu-pubnames.s
    M lld/test/ELF/gdb-index.s

  Log Message:
  -----------
  [ELF] Drop .rel[a].debug_gnu_pub{names,types} for --gdb-index --emit-relocs

Fixes PR48693: --emit-relocs keeps relocation sections. --gdb-index drops
.debug_gnu_pubnames and .debug_gnu_pubtypes but not their relocation sections.
This can cause a null pointer dereference in `getOutputSectionName`.

Also delete debug-gnu-pubnames.s which is covered by gdb-index.s
