  Log Message:
  -----------
  [AsmPrinter] Don't generate .Lfoo$local for -fno-PIC and -fPIE

-fno-PIC and -fPIE code generally cannot be linked in -shared mode and there is no benefit accessing via local aliases.

Actually, a .Lfoo$local reference will be converted to a STT_SECTION (if no section relaxation) reference which will cause the section symbol (sizeof(Elf64_Sym)=24) to be generated.
