This is the base class for function scopes.  Subclasses of this class are
produced by the ObjectClassGenerator along with additional fields for storing
local vars.  The number of fields required is determined by ObjectCreator.
The scope is also responsible for handling the var arg 'arguments' object,
though most of the access is via generated code.
The constructor of this class is responsible for any function prologue
involving the scope.
