Force byteable register for CMP if op2 is CNS_INT
On x86 we need to force byteable registers for compares not only when both
ops are typ_byte, but also when the first is of typ_byte and the second is
a constant int. The original condition for cmp only considered the first
case. This change adds the second condition.
