78ee3759b8 x86-asm: Fix lcall/ljmp, xchg and inc/dec 
Various x86 asm fixes: 64bit lcall/ljmp like 32bit a commit before,
xchgw accepted wrong operands on 32 and 64bit, and 64bit used
0x40/0x48+reg for incw/decw, but those are REX prefixes, not
instructions.

eb870b006c 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

47e06c6d4e Reorganize the source tree. 
* Documentation is now in "docs".
 * Source code is now in "src".
 * Misc. fixes here and there so that everything still works.

I think I got everything in this commit, but I only tested this
on Linux (Make) and Windows (CMake), so I might've messed
something up on other platforms...

e260b03686 Allow tcc to understand a setob,... opcodes as alias to seto,... 
PS: http://lists.cs.uiuc.edu/pipermail/llvm-commits/Week-of-Mon-20101122/112576.html
This is fix PR8686 for llvm: accepting a 'b' suffix at the end
of all the setcc instructions.

a1a691a030 Detect correct instruction with incorrect operands 
Display a different warning when an instruction is recognized by tcc but
the operands found do not correspond to the constraints of the
instruction.
