I guess you want to let the code more efficiently with pulling out E->getType()
?
but
1. if I pull out E->getType() , it means that E->getType() will be run in the
all call flow path even `SupportOP == OP_EQ`, which do not need the
E->getType().
2. the `E->getType()` only be called once at maximum at each call flow path.
