SSE registers are v4sf only, but SSE2 registers (Pentium 4) are
v2df, v4sf, v16qi, v8hi, v4si, and v2di. I don't believe GDB supports
them yet.

I would like to see us treat all SIMD registers in the same manner, not
just Altivec. Even though the packing and size will vary, the display
syntax should be consistent.
