This uses split DWARF and from looking at other tests, it should not be
running on Darwin or Windows.
It does pass using the DIA PDB plugin but I think this is misleading
because it's not actually testing the intended feature.
When the native PDB plugin is used it fails because it cannot set a
breakpoint. I don't see a point to running this test on Windows at all.
Native PDB plugin test failures are being tracked in #114906.
