/**
* OTDT changes:
*
* STRUCTURE:
* ==========
* What: Additional, OT-specific info is in a MethodModel instance, which
* is associated to a method binding, as needed.
* Note: This MethodModel has to be passed along every time a new MethodBinding
* is created either from AST or from another MethodBinding.
*
* What: New flags copyInheritanceSrc and overriddenTSuper
* Both flags link to a tsuper version, the first for purely
* copied methods, the latter for overriding methods.
* Why: Mainly, ConstantPoolObjectMapper needs these links to find
* tsub-versions of method bindings retrieved from the source method.
* Further notes on copyInheritanceSrc:
* + this field is furthermore used as a flag to signal that
* this method is a pure copy.
* + during CopyInheritance it is transitively followed, to actually
* enter the original version of a method that is copied along
* several levels.
* + While resolving types for binary methods, this field is set
* similarily as during CopyInheritance.
* + It is used during error reporting to mention the source-method
* not any copy.
*
*
*
* What: Analysis for calls to a base-constructor.
* Why: Constructors of bound roles (other than the lifting constructor)
* must directly or indirectly invoke base().
*
*
* Runtime checks in role creation methods are scattered over these classes:
* + AllocationExpression.resolveType
* detect unsafe use of lifting constructor
* -> record in MethodBinding.roleCreatorRequiringRuntimeCheck
* + AbstractMethodDeclaration.generateCode(ClassFile)
* if roleCreatorRequiringRuntimeCheck is set:
* -> call Lifting.createDuplicateRoleCheck to create the byte code sequence
*
