JDK-8339167 - Remove AbstractPoolEntry.PrimitiveEntry to reduce boxing overheads
Description
Constant pool entry tag field is redundant information given they are already bound by class; we can use overrides instead.

Removal of hash field was considered, but as trivial as hash computation seems, it takes cpu cycles and the hash field is a smaller overhead in comparison.
