Unfortunately I don't think so. Given where the test failures are (clang linked with LLD), I think that this may be a problem in the clang executable or shared-library itself causing it to miscompile the tests. If I'm right I think we'll need to find where the differences are in the before and after build then track back to the merge sections in the original objects.
