/**
* A common base class for frame modeling visitors. This class provides a
* default implementation which copies values between frame slots whenever
* appropriate. For example, its handler for the ALOAD bytecode will get the
* value from the referenced local in the frame and push it onto the stack.
* Bytecodes which do something other than copying values are modeled by popping
* values as appropriate, and pushing the "default" value onto the stack for
* each stack slot produced, where the default value is the one returned by the
* getDefaultValue() method.
*
*
* Subclasses should override the visit methods for any bytecode instructions
* which require special handling.
*
*
* Users of AbstractFrameModelingVisitors should call the analyzeInstruction()
* method instead of directly using the accept() method of the instruction. This
* allows a checked DataflowAnalysisException to be thrown when invalid bytecode
* is detected. E.g., stack underflows.
