[AIX][ZOS] Disable LIT tests on AIX and z/OS due to lack of Objective-C support

[Jake-Egan]

Summary

AIX and z/OS lack Objective-C support, so mark these tests as unsupported for AIX and z/OS.

[jsji]

For clang/test/CodeGenObjCXX and clang/test/CodeGenObjC, can we add lit.local.cfg and add the unsupport there, no adding to every files in the folder?

These tests are a subset of clang/test/CodeGenObjCXX and clang/test/CodeGenObjC. The rest of the tests in those folders are supported (cross-compiling).

We don't have Objective-C support, so any passing tests are just somehow a luck, and I don't think it is meaningful to even run those tests.

[Jake-Egan]

Added lit.local.cfg and unsupported z/OS as well.

[jsji]

LGTM. Thanks!

Fixed ExtDebugInfo.cpp

[jsji]

clang/test/Modules/ExtDebugInfo.cpp

209

Why this change? If this is needed, this should be in another patch. Thanks.

[Jake-Egan]

clang/test/Modules/ExtDebugInfo.cpp

209

The test failed in Debian and Windows because the unsupported line I added changed the expected line number: 27->28.
https://reviews.llvm.org/D109060?id=371137

Without this change, this patch would cause a regression. But, I can put it in another patch if that's preferred.

[jsji]

clang/test/Modules/ExtDebugInfo.cpp

209

In that case, I would recommend we update it to regex match instead of hardcoding line no, and yes, in another patch before this.

[Jake-Egan]

Revert last ExtDebugInfo.cpp change because https://reviews.llvm.org/rG45a738363ee39754a0e93d9f779bda2cad83fa18 has been committed.
