making unsigned and signed types
incompatible caused regressions: see this excerpt from
http://gcc.gnu.org/ml/gcc-patches/2004-03/msg00843.html

    "The same is for gcc.dg/simd-1.c and gcc.dg/20020531-1.c, where one was
    checking for incompatibility between vector types with different
    signedness but the same mode, and the other was happily passing an
    unsigned V8QI to __builtin_ia32_paddusb which expects a signed V8QI.
    I fixed gcc.dg/simd-1.c to not expect an error on vector types with
    the same mode but different signedness."
