test/tools/llvm-objdump/X86/plt-got.test

## If a symbol needing a PLT entry also needs a GLOB_DAT relocation, GNU ld's
## x86 port places the PLT entry in .plt.got, relocated by a GLOB_DAT. The
## JUMP_SLOT relocation is unused in this case.
## Test that we synthesize @plt symbols for such PLT entries.
