Added new tree walker helper optHasCSEdefWithSideeffect to determine up front if we have
a nested CSE def with side effects.  The refs counts will be wrong when we start unmarking
some CSE uses and then later abandon the replacement operation.
So now we decide upfront if we have a CSE def with side effects before we call optUnmarkCSEs.
