    [dsymutil] Avoid copying binary swiftmodules built from textual
    
    .swiftinterface files into the dSYM bundle. These typically come only
    from the SDK (since textual interfaces require library evolution) and
    thus are a waste of space to copy into the bundle.
    
    The information about this is being parsed out of the control block,
    which means duplicating 5 constants from the Swift frontend. If a file
    cannot be parsed, dsymutil errs on the side of copying the file
    anyway.

    Relanding with additional linker dependency and moving the test into
    the right target subdirectory.
