[lld] Add REQUIRES: x86 where needed to tests If building lld without x86 support, tests that require that support should be treated as unsupported, not errors. Tested using: 1. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64;X86' make check-lld => Expected Passes : 1406 Unsupported Tests : 287 2. cmake '-DLLVM_TARGETS_TO_BUILD=AArch64' make check-lld => Expected Passes : 410 Unsupported Tests : 1283 Patch by Joel Jones Differential Revision: https://reviews.llvm.org/D47748 llvm-svn: 334095

# REQUIRES: x86
[ELF] - Teach LLD to use information from .debug_str for error reporting. Recently we teached LLD to report line numbers for duplicate variables definitions, though currently LLD is unable to do that for case when strings are not built in .debug_info, but stored in .debug_str instead. That is because out LLDDwarfObj does not handle .debug_str yet. Patch fixes that. Differential revision: https://reviews.llvm.org/D39542 llvm-svn: 318519
