Details

This entails changing js::array_concat in jsarray.cpp to use the (to-be-introduced) IsConcatSpreadable abstract operation instead of ObjectClassIs in the items loop.
Possibly bug 688852 should land before this changes. Or, possibly we should just drop that patch/bug entirely and fix that bug here with a self-hosted version. :-\
