Fangrui Song 537a5bfb7f [ELF] Allow --noinhibit-exec to produce corrupted executable with relocation overflow 
Summary:
When --noinhibit-exec is used, ld.bfd/gold emit errors but allow to produce corrupted executable, which is handy for debugging purpose. lld's --noinhibit-exec has a different meaning and changes some errors to warnings. This patch replaces "error" with "errorOrWarn" to exploit that property.

We may revisit this: if we should keep them as errors (as ld.bfd/gold do) but allow to produce a (corrupted) executable.

Joel Jones a5752e199c [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
