prohibits bools as gcc-vectors

Hi,

I've already posted this to cfe-commit. I don't know whether you prefer patches
here or via the mailing list.

this simple program currently causes a crash:

typedef bool  bxmm __attribute__ ((vector_size(16)));
typedef float fxmm __attribute__ ((vector_size(16)));

bxmm f(fxmm a, fxmm b) {
    return a < b;
}

The reason for this is that actually bools are not allowed to be declared as
gcc-vectors. (At least gcc does not allow this).
The attached patch fixes this issue by emitting an error message when using
bools in gcc-vectors.

This was tested on current trunk. I guess that current 3.1 branch has the same
problem but I haven't looked into it or tried it.
