The IL language does not contain all the possible comparisons that could be
generated. For example, there is no compare-lt-or-eq. You have to generate
cgt / ldc.i4.0 / ceq.

But the operations to do this do exist in assembly (at least for the x86),
but we do not use them. Consider the following code:

class T {
	static void Main () { B (); }
	
	static bool B ()
	{
		int i = 0;
		int j = 1;
		
		return i <= j;	
	}
}

We generate:

   f:	bf 00 00 00 00       	mov    edi,0x0
  14:	be 01 00 00 00       	mov    esi,0x1
  19:	8b c6                	mov    eax,esi
  1b:	3b f8                	cmp    edi,eax
  1d:	0f 9f c0             	setg   al
  20:	0f b6 c0             	movzx  eax,al
  23:	85 c0                	test   eax,eax
  25:	0f 94 c0             	sete   al
  28:	0f b6 c0             	movzx  eax,al

Clearly, we could optimize this down to one cmp operation.

ooops, i filed this twice. Marking the older bug as a dup because the
newer one has a patch.
