[ELF] - Add a test for --gc-sections --undefined=foo combination. GC code contains following logic uncovered by tests: for (StringRef S : Config->Undefined) MarkSymbol(Symtab->find(S)); As far I can tell we never had test for that before, patch fixes it. Differential revision: https://reviews.llvm.org/D36519 llvm-svn: 310556

# REQUIRES: x86
# RUN: llvm-mc -filetype=obj -triple=x86_64-unknown-linux %s -o %t
# RUN: ld.lld %t -o %t1 --gc-sections --undefined=foo
[test] Change llvm-readobj -long-option to --long-option or well-known short options. NFC Also change some options that have different semantics (cause confusion) in llvm-readelf mode: -s => -S -t => --symbols -sd => --section-data llvm-svn: 359651
