Description:

BRProgramNodeVisitor is an abstract visitor for the BRProgramNodes.

cg: I have made it half-concrete, by allowing for a node-action to be
set. This allows for very lightweight use in search for something applications.

Class protocol:

 new

(comment from inherited method)
return an instance of myself without indexed variables

Instance protocol:

 pluggableNodeAction: something

 copy

Here since IBM doesn't do postCopy's

 postCopy

 initialize

 visitArgument: each

Here to allow subclasses to detect arguments or temporaries.

 visitArguments: aNodeCollection

returns aNodeCollection (actually: whatever its do: method returns)
(not sure if it must do so, or if it is sloppy programming)

 visitNode: aNode

 acceptArrayNode: anArrayNode

that's a squeak constructed array

 acceptAssignmentNode: anAssignmentNode

 acceptBlockNode: aBlockNode

 acceptCascadeNode: aCascadeNode

 acceptLiteralNode: aLiteralNode

 acceptMessageNode: aMessageNode

 acceptMethodNode: aMethodNode

 acceptOptimizedNode: anOptimizedNode

 acceptPragmaNode: aPragmaNode

 acceptReturnNode: aReturnNode

 acceptSTXPrimitiveCCodeNode: aPrimitiveCCodeNode

 acceptSTXPrimitiveValueCCodeNode: aPrimitiveValueCCodeNode

 acceptSequenceNode: aSequenceNode

 acceptVariableNode: aVariableNode

 passByNode: aNode

called when we passed by some node, aNode.
Can be redefined in a subclass to track any visited node
(without a need to redefine all of the accept***Node methods) in a subclass
