96fd76638b add integer overflow check for the fp induction variable 
checker.  Amusingly, we already had tests that we should
have rejects because they would be miscompiled in the
testsuite.

The remaining issue with this is that we don't check that
the branch causes us to exit the loop if it fails, so we
don't actually know if we remain in bounds.

43b85273ee fix PR6761, a miscompilation due to the fp->int IV conversion 
stuff.  More bugs remain though.
