on ia32. 1. Operate on the values in edx,eax when possible (all operations except DIV and MOD). This saves moving them on entry and when falling out to the non-smi code. 2. Do not perform ADD and SUB before the smi check of their inputs. This saves undoing the operation in the case that we fall through to the non-smi case due to non-smi inputs (probably common?), and we can avoid emitting the smi check code twice (code size reduction). 3. Don't perform OR twice (once to smi check the inputs and once to smi check the result).
