- Store the JS value, so the conversion happens when the backtrace is needed
- Prevent recursion in build_backtrace
- Simplify code for saving / restoring exception in build_backtrace

@bnoordhuis PTAL, let me know what you think. It ended up a bit more complex that I originally envisioned. Alternative: convert the value on the spot and store both the JS value and the converted value, and use the latter in build_backtrace. Thoughts? |

@bnoordhuis Updated, can you PTAL one more time? |

You don't have to cast to double (but it doesn't hurt either, it's just a no-op)
The isinf(d) && d < 0.0 two lines up looks superfluous. You check d < 0.0 first and -Infinity < 0.0

Right. Does the same apply to checking for positive infinity? It will be larger than INT32_MAX I guess.

Good point. By an infinite amount, according to mathematicians.
