c40a640555 Bug 1605348 - Only trace the target of a WeakRef if the tracer requests weak edges r=sfink 
The problem is the compartment checking tracer currently gets to see the target of a WeakRef, which may be in another compartment. I updated the trace method to check the traceWeakEdges() flag and set this to false for the GCMarking tracer. I was surprised that this wasn't the case before but I did a try run and everything looks fine.

8b73371be0 Bug 1407593 - Report embedding leaks of JS GC things r=sfink,sfink? 
Patch to report JS GC things that are live at shutdown as leaks by calling MOZ_LOG_CTOR for them. The JS engine now clears any remaining roots to prevent dangling pointers to freed memory after shutdown. I made XPCJSRuntime::Shutdown keep the weak pointer update callbacks as sometimes these tables have entries remaining at shutdown (if there are leaks) and we need the callbacks to update them.

This is looking more green on try now.

b425876903 Bug 1306008 - Give JS::Heap<T> pointer wrappers a pre-barrier r=sfink 
This adds a pre write barrier to Heap<T> so that these can be uses as non-roots in the heap without breaking our snapshot at the beginning invariant if they are written to during an incremental GC. This makes it harder to misuse and allows us to take out manual barriers in at least one place.

6c4a1d23f2 Bug 1460636 - Don't trace jsids on ObjectGroup in the cycle collector. r=jonco,sfink 
For some reason, the CC spends a lot of time tracing jsids on
ObjectGroups when an addon is installed. This patch avoids that by
adding a canSkipJsids flag to JSTracer, and using it in
ObjectGroup::traceChildren. If this is true, then the tracer is free
to not report every jsid. This flag is set to true for the two CC
tracers.

1685818a63 Bug 1254092 - TraceIncomingCCWs should work at the JSCompartment level of granularity. r=jimb 
There can be multiple compartments within the same zone, only one of which is a
debuggee. In this scenario, CCWs from other compartments into the debuggee
compartment should be traced and treated as roots. Therefore, dealing with CCWs
at the JS::Zone level is incorrect, and this patch changes the granularity level
to JSCompartments. If you look at the callers and uses of the function, it makes
much more sense now.

Additionally, it renames `JS_TraceIncomingCCWs` to `JS::TraceIncomingCCWs`.
