[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
Reject zero-sized symbols when creating copy relocations. Copy relocations are relocations to copy data from DSOs to executable's .bss segment at runtime. It doesn't make sense to create such relocations for zero-sized symbols. GNU linkers don't agree with each other. ld rejects such relocation/symbol pair. gold don't reject that but do not create copy relocations as well. I took the former approach because I don't think the latter is what user wants. llvm-svn: 270525

Don't depend on "call foo" producing a X86_64_PC32. Newer versions of the gnu assembler produce a X86_64_PLT32 for calls. There is a change under review in llvm to do the same, so update the tests to not depend on it. We can still produce a R_X86_64_PC32 with ".long foo - .". llvm-svn: 325379
