    [PATCH, rs6000] Fix vector long long subtype (PR96139)

    Hi,
    This corrects an issue with the powerpc vector long long subtypes.
    As reported by SjMunroe, when building some code with -Wall, and
    attempting to print an element of a "long long vector" with a
    long long printf format string, we will report an error because
    the vector sub-type was improperly defined as int.

    When defining a V2DI_type_node we use a TARGET_POWERPC64 ternary to
    define the V2DI_type_node with "vector long" or "vector long long".
    We also need to specify the proper sub-type when we define the type.

    Due to some file renames, This is a backport and rework of both
        [PATCH, rs6000] Fix vector long long subtype (PR96139)
    and
        [PATCH, rs6000] Testsuite fixup pr96139 tests
