This is a follow-up to Bug 1426124. Most of the unsymbolicated JIT frames are removed from the native frames, but there are still a few that need to be filtered out. These are the ones going from Ion -> C++ code.

jandem recommended finding them through:

> The exit frame when we go from JIT -> C++: this one I'm not sure about, maybe we can check |endStackAddress - X| or so instead of endStackAddress.

The trick here is to figure out what the X should be. Perhaps some investigation will reveal a place that we can measure against.

Thanks Panos for making this aware of this bug.  I will add this to our list of profiling related bugs we are tracking and working on.  I will eventually create a tag or Meta bug for these.
