      PrimitiveEntry is today an intermediate abstract base class for Integer-/Long-/Float-/DoubleEntryImpl. This abstraction seem to have little benefit (some code reduction), but leads to code that need to match the correct ClassFile.TAG_* constant with an appropriate cast, excess boxing and unboxing etc. Removing it brings a tiny win on startup.
