Issue #2083 - Part 1: Make RegExpShared a GC thing.

Browse source 
Based on Mozilla bug 1345177.
Changes from the original bug's patch:

- We don't have JS::CurrentThreadIsHeapCollecting, so let's use
  trc->runtime()->isHeapCollecting() instead.
- Mozilla bug 1337117 renamed runtimeFromMainThread to
  runtimeFromActiveCooperatingThread for Firefox 54, so let's use the former
