Details

As followup to Bug 1419372, there is possibly room to implement a typed version of the pre-existing IonMonkey optimization IonBuilder::inTry (https://searchfox.org/mozilla-central/source/js/src/jit/IonBuilder.cpp#12839) Adding inline caching should do the majority of the heavy lifting (Patches in 1419372), but this should help Typed array in catch up to it's untyped neighbour.
