Summary:
when run "llvm-ar cr" on AIX OS , it created a gnu archive, it is not desirable in aix OS.
instead of creating a gnu archive, the patch will print a unsupport message for llvm-ar big archive write operation in AIX OS.
after implement the big archive operation, I will revert the XFAIL: AIX " and "--format=gnu" test cases in the patch.

When adding an archive member with a problem, e.g. a new bitcode with an
old archiver, containing an unsupported attribute, or an ELF file with a
malformed symbol table, the archiver would throw away the error and
simply add the member to the archive without any symbol entries. This
meant that the resultant archive could be silently unusable when not
using --whole-archive, and result in unexpected undefined symbols.
This change fixes this issue by addressing two FIXMEs and only throwing
away not-an-object errors. However, this meant that some LLD tests which
didn't need symbol tables and were using invalid members deliberately to
test the linker's malformed input handling no longer worked, so this
patch also stops the archiver from looking for symbols in an object if
it doesn't require a symbol table, and updates the tests accordingly.
