3dca490ff0 Fix typo in packsswb instr definition, where the load had the wrong type. 
This allows us to use the multiclass for other packs.

(load x+8), (load x+12), <0, 1, 2, 3> to a single 128-bit load (aligned and
unaligned).

e.g.

__m128 test(float a, float b, float c, float d) {
  return _mm_set_ps(d, c, b, a);
}

a7fc64222a Added X86 SSE2 intrinsics which can be represented as vector_shuffles. This is 
a temporary workaround for the 2-wide vector_shuffle problem (i.e. its mask
would have type v2i32 which is not legal).

017dcc6e55 Now generating perfect (I think) code for "vector set" with a single non-zero 
scalar value.

==>
	movd 4(%esp), %xmm0
	pshufd $69, %xmm0, %xmm0

        _mm_set_epi8(0, 0, 0, 0, 0, a, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0);
==>
	movzbw 4(%esp), %ax
	movzwl %ax, %eax
	pxor %xmm0, %xmm0
	pinsrw $5, %eax, %xmm0
