[ELF] - Allow LLD to produce file symbols. This is for PR36716 and this enables emitting STT_FILE symbols. Output size affect is minor: lld binary size changes from 52,883,408 to 52,949,400 clang binary size changes from 83,136,456 to 83,219,600 Differential revision: https://reviews.llvm.org/D45261 llvm-svn: 329557
