Add sentinel_ok() check to BumpCheck(). Effectively an oversight in 29f6a959cf. The code went to the trouble of doing set_sentinel() but no code ever checked it was still set during BumpCheck(). Since bump context types are used in a handful of places, it very much makes sense to backpatch this to where bump.c was added so we can more easily discover any memory stomping bugs.
