Jeremy Hylton c59e220000 Handle private names
(Hard to believe these were never handled before)

Add misc.mangle() that mangles based on the rules in compile.c.
XXX Need to test the corner cases

Update CodeGenerator with a class_name attribute bound to None.  If a
particular instance is created within a class scope, the instance's
class_name is bound to that class's name.

Add mangle() method to CodeGenerator that mangles if the class_name
has a class_name in it.

Modify the FunctionCodeGenerator family to handle an extra argument--
the class_name.

Wrap all name ops and attrnames in calls to self.mangle()

Jeremy Hylton 314e3fb215 Change the graph structure to contain the code generator object for
embedded code objects (e.g. functions) rather than the generated code
object.  This change means that the compiler generates code for
everything at the end, rather then generating code for each function
as it finds it.  Implementation note: _convert_LOAD_CONST in
pyassem.py must be change to call getCode().

Other changes follow.  Several changes creates extra edges between
basic blocks to reflect control flow for loops and exceptions.  These
missing edges had gone unnoticed because they do not affect the
current compilation process.

pyassem.py:
    Add _enable_debug() and _disable_debug() methods that print
    instructions and blocks to stdout as they are generated.

    Add edges between blocks for instructions like SETUP_LOOP,
    FOR_LOOP, etc.

    Add pruneNext to get rid of bogus edges remaining after
    unconditional transfer ops (e.g. JUMP_FORWARD)

    Change repr of Block to omit block length.

pycodegen.py:
    Make sure a new block is started after FOR_LOOP, etc.

    Change assert implementation to use RAISE_VARARGS 1 when there is
    no user-specified failure output.

misc.py:
    Implement __contains__ and copy for Set.
