New Revision: 71504

Added:
   pypy/branch/guard-value-counting/
      - copied from r71503, pypy/trunk/
Log:
A branch in which to try the following idea: on failing GUARD_VALUE,
put not just one counter but one counter per value.  This should help
because a GUARD_VALUE that keeps seeing new values is not useful to
start tracing from.
