Following up from https://github.com/llvm/llvm-project/pull/76244, this patch re-enables one of the OrcLazy debug tests on macOS. Previously these tests were forcing in-memory objects to ELF format. Now they use the native format. As noted inline, the `debug-objects.ll` test doesn't work for Mach-O yet. @aeubanks Once this lands, please let me know if this causes issues on your bots.
