      javac currently generates the equals/hashCode/toString method for inline type that is a indy call to ValueBootstrapMethods::makeBootstrapMethod

      `==` has been implemented for inline types and hence the equals method synthesized in an inline class can be dropped.

      The current implementation of Object::hashCode is an identity hash code. This issue is to investigate if VM can call ValueBootstrapMethods::hashCodeInvoker for inline types (similar to substitutability test) and stores the hash code in the object header.
