SSE opcodes to TCC assembler (i386, x86_64)

    patch from Anaël Seghezzi
    a test program:
    ============================
    #include <stdio.h>
    struct fl4{ float x, y, z, w; };
    void asm_test(void)
    {
	struct fl4 v1, v2, v3;
	v1.x = 0.1;
	v1.y = 0.2;
	v1.z = 0.4;
	v1.w = 0.3;
	v2.x = 0.11;
	v2.y = 0.0;
	v2.z = 0.01;
	v2.w = 0.04;
	asm volatile (
	    "movups %0, %%xmm0;"
	    "movups %1, %%xmm1;"
	    "addps %%xmm1, %%xmm0;"
	    "movups %%xmm0, %2"
	:: "g" (v1), "g" (v2), "g" (v3) : "memory");
	printf("sse fl4 add : %f %f %f %f\n", v3.x, v3.y, v3.z, v3.w);
	printf("expected : %f %f %f %f\n", v1.x+v2.x, v1.y+v2.y, v1.z+v2.z, v1.w+v2.w);
    }
    int main() { asm_test(); }
    /*
	sse fl4 add : 0.210000 0.200000 0.410000 0.340000
	expected : 0.210000 0.200000 0.410000 0.340000
    */
