Delay and be selective about when to discard local types
jit_rb_obj_not() wants to access the type information of the receiver, but we were discarding type info of locals before jit_rb_obj_not() runs unncessarily.
There are also cases we are unncessarily discarding local type info. For example, ivar reader and setter methods can never change local variables.
