Fix DevDiv bug 359737.

This bug was an assertion during CSE that ensures that all CSE
candidates have value numbers. This assertion tripped because an earlier
CSE in the same tree as the faulty candidate re-morphed modulus by a
constant into a divide and subtract; the resulting tree was left without
value numbers. This change disables the problematic transform when
remorphing as part of CSE.
