Some lit tests that call llvm-ar use the 'r' flag. If the target archive
already exists and is in a corrupt state, this can cause the test to fail. We
have added 'rm -f' calls before the llvm-ar calls to increase the
robustness of the 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

The code generator may create references to runtime library symbols such as
__chkstk which were not visible via LTOModule. Handle these cases by loading
the object file from the library, but abort if we end up having loaded any
bitcode objects.
Because loading the object file may have introduced new undefined references,
call reportRemainingUndefines again to detect and report them.
