The fix outlined in bug 465484 causes a performance regression for tamarin in misc/primes
- sending to qrb for target milestone, this is marked as a blocker for the TM/TR nanojit merge so needs to be targeted from this release
- will be able to track perf change using mentioned performance micro benchmark:

re-opening to track the work of improving the good-enough fix that is in place now.  The existing fix causes a 5% slowdown in misc/primes.as, but negligible slowdown in the rest of the tests.
