[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

[COFF] Fix SECREL and SECTION relocations against common symbols Summary: They do the obvious thing: provide the section index of .bss and the offset of the symbol in .bss. Reviewers: ruiu Subscribers: llvm-commits Differential Revision: https://reviews.llvm.org/D34628 llvm-svn: 306304

COFF: Layout sections in the same order as link.exe One place where this seems to matter is to make sure the .rsrc section comes after .text. The Win32 UpdateResource() function can change the contents of .rsrc. It will move the sections that come after, but if .text gets moved, the entry point header will not get updated and the executable breaks. This was found by a test in Chromium.
