This patch removes two redundant computations in copyprop:

* Before, we would visit each inst to check for kill effects. However, we
only need to do this if there are variables whose address has been taken.

* Since cprop already calls the cfold pass, there is no need to do a
seperate round of constant folding.

Together, these changes make it so that -O=copyprop does not impact jit time.
