Implement the -dynamic-linker option. With this dynamic executables can be executed with just ./t instead of /lib64/ld-2.20.so ./t llvm-svn: 247446

Start adding support for creating shared libraries. They are not fully functional yet, but this implements enough support for lld itself to read them. With that, delete the .so binary we were using for tests and start eating our own dog food. llvm-svn: 247487

[ELF2] Initial support for local symbols. Symbol table is now populated correctly, but some fields are missing, they'll be added in the future. This patch also adds --discard-all flag, which was the default behavior until now. Differential Revision: http://reviews.llvm.org/D12874 llvm-svn: 247849
