D122746 missed the following tests, so this patch adds them.
This patch refactors D122949, which marked the following tests XFAIL, but it makes more sense to temporarily add `--format=gnu` option because these tests aren’t testing `llvm-ar` and AIX won’t lose their coverage.

Big archive writer operation is not currently supported so mark these tests XFAIL for now.

llvm-link should not rely on the '.a' file extension when deciding if input file
should be loaded as archive. Archives may have other extensions (f.e. .lib) or no
extensions at all. This patch changes llvm-link to use llvm::file_magic to check
if input file is an archive.

This patch adds support for archive files as inputs to llvm-link. One
of the use-cases is for OpenMP, where device specific libraries need
to be extracted from libraries containing bundled object files. The
clang-offload-bundler will support extracting these archives, which
will be passed into llvm-link, see https://reviews.llvm.org/D80816.
