Handle versioned undefined symbols. In order to keep symbol lookup a simple name lookup this patch adds versioned symbols with an explicit @ to the symbol table. llvm-svn: 291293

ELF: Place relro sections after non-relro sections in r/w segment. This is in preparation for my next change, which will introduce a relro nobits section. That requires that relro sections appear at the end of the progbits part of the r/w segment so that the relro nobits section can appear contiguously. Because of the amount of churn required in the test suite, I'm making this change separately. llvm-svn: 291523
