Garbage-collect common symbols. Liveness is usually a notion of input sections, but this patch adds "liveness" bit to common symbols because they don't belong to any input section. This patch is based on https://reviews.llvm.org/D36520 Differential Revision: https://reviews.llvm.org/D36546 llvm-svn: 310617

[ELF] Remove checking for spurious '@' at the end of dynamic sym names llvm-readobj currently has a bug (see PR40097) where it prints '@' at the end of unversioned dynamic symbols. This bug will be fixed in a separate later commit, but these tests need fixing first. Reviewed by: ruiu, Higuoxing Differential Revision: https://reviews.llvm.org/D56388 llvm-svn: 350614
