    Use a single "jit_marker" operation for all jit-oriented markers.

    Make all the 'tryfold' operations directly runnable too,
    for example all ovf-checking arithmetic.
    (done by moving their implementation from llinterp.py to opimpl.py)

    A second test and the code to make it pass.  It introduces green vars
    and it's a real interpreter over a bytecode with loop support.
    
    Quiz: in this bytecode, what is the following function doing?
    'ISRDD{ISR%?SDD*}S'

    An oversight in the jit-refactoring.txt: after the fallback interpreter
    finishes we need to pass new values for the red=(..) and green=(..)
    variables of jit_merge_point().  Solved by splitting the portal graph in
    three graphs, the middle one being a wrapper that catches a
    ContinueRunningNormally exception carrying the new values.

    A branch off the jit-refactoring branch to start playing with
    the hotpath approach described in jit-refactoring-plan.txt.
    
    This is all experimental.  Some of the changes in this branch might be
    easy to merge back if the approach seems to work, but some not.  Anyway
    for now I will just go ahead and whack at code just to try things out
    without worrying about merging.

    Move the special-casing of ComputedIntSymbolic into opimpl.py.
    Allows the llop.int_xxx() operations to operate on them.
