[cc2-qbe] Small stetic changes to the output of qbe

After this commit we have a beatitul output for something like

$ cc1 | cc2
int
func(int a, int b)
{
	int c;

	c = a + c;
}
^D
export function h $func(h %a,h %b)
	%c h=	alloc2	2
	$.1 w=	load	%a
	$.2 w=	load	%c
	$.3 w=	add	$.1,$.2
		storew	$.3,%c
}
