Two changes...

- Teach all the integer/float predicates on Type about Vectors.
- Disallow bitwise compliment on float vectors. For example...

typedef float __attribute__(( vector_size(16) )) float4;

float4 float4_return()
{
    float4 xx;

    return ~xx;
}

...now emits the following diagnostic...

[administrators-powerbook59:~/llvm/tools/clang] admin% ../../Debug/bin/clang bug.c
bug.c:8:12: error: invalid argument type to unary expression 'float4'
    return ~xx;
           ^
