8267923: [lworld] Javac's implementation differs from JEP401 in a few matters.

[sadayapalam]

Cumulative fix for the following issues:

JDK-8267918 - Javac tolerates synchronizing on a primitive reference type
JDK-8267907 - Withdraw support for the experimental option -XDallowValueMemberCycles
JDK-8267843 - Duplicate error when primitive class instance is passed around before being fully initialized
JDK-8267841 - A primitive class that implements Cloneable is tolerated by javac
JDK-8267835 - Javac tolerates vacuous chaining to super constructor from primitive class constructor
JDK-8267965 - Javac disallows calls to super.{hashCode(), equals(), toString()} on a primitive instance receiver
