Add -disable-llvm-passes for frontend debug info tests.

Summary

The frontend debuginfo tests should not invoke llvm passes which includes add-discriminators that will change the debug info generated by FE.

Welcome to commit this sort of thing without pre-commit review (though if you want review it should go to cfe-commits rather than llvm-commits)

I imagine we want to preserve this comment - I guess that's what this test looked like before discriminators were added to it?
