    Add support for passing SSE vectors in registers.
    
    This patch adds support for 6 XMM registers on x86-64 which overlap with the F
    and D registers and may hold 128-bit wide SIMD vectors. Because there is not a
    good way to attach type information to STG registers, we aggressively bitcast in
    the LLVM back-end.
