4662c498be Bug 1324140 - Unwrap given Promise in some JSAPI functions. r=bz 
To make Promise-related JSAPI functions easier to use, this patch unwraps handed-in Promise objects automatically. Some functions don't unwrap, mostly debugging-related ones and, notably, JS::IsPromiseObject. The latter doesn't unwrap in order to stay conservative: if JSAPI-using code uses IsPromiseObject to verify that an object is a Promise, it should always be fine to say "no".

bb2fc6efce Bug 1360372 - Avoid rooting hazard when entering atoms compartment (r=sfink) 
This patch avoids a rooting hazard involving the atoms compartment. There is
code in jsatom.cpp that enters the atoms compartment while unrooted pointers
are on the stack. Now that enterZoneGroup can potentially yield, this leads to
a rooting hazard. This patch avoids the hazard by using a totally separate path
that avoids enterZoneGroup when entering the atoms compartment.

9862d9c932 Bug 1359245 - Remove some tracing callbacks at shutdown (r=mccr8) 
When we just had CycleCollectedJSContext (and no CycleCollectedJSRuntime) a
weird thing happened at shutdown:
1. We would call JS_DestroyContext from ~CycleCollectedJSContext. By that time,
   the ~XPCJSContext destructor had already finished.
2. Destroying the context runs a final GC. That GC would call back into various
   GC callbacks, such as TraceBlackJS and TraceGrayJS.
3. These callbacks would do a virtual method call:
   http://searchfox.org/mozilla-central/rev/876c7dd30586f9c6f9c99ef7444f2d73c7acfe7c/xpcom/base/CycleCollectedJSRuntime.cpp#791
4. Normally this method call would call into
   XPCContext::TraceNativeBlackRoots. However, C++ changes the vtable for an
   object during destruction. So we would only call CycleCollectedJSContext's
   version of TraceNativeBlackRoots, which is empty. So we never traced anything.

When I moved this code into the runtime, we actually do call into
XPCJSRuntime::TraceNativeBlackRoots at that time. So the behavior changed, and
that was causing crashes once I nulled out the TLS as you asked. So I removed
these callbacks for the last GC.

1d5c5ef48b Bug 1359245 - Keep a linked list of CycleCollectedJSContexts in the runtime (r=mccr8) 
This patch keeps a list of all the cooperatively scheduled contexts that are
linked to a runtime. In places where we need to iterate over all contexts (for
GC, specifically), it iterates over the list.

This field assumes there is one XPCJSContext globally (i.e., per nsXPConnect
instance). This patch eliminates the field by using different paths to
reach the context.

133ed14a85 Bug 1359245 - Eliminate some XPCJSContext::Get() usage (r=mccr8) 
XPCJSContext::Get() now does a TLS lookup, which is a little more expensive
than looking up a global variable. This patch removes as many of the TLS
lookups as possible.

Once we have multiple XPCJSContext's, we may have to figure out which one we're
using with TLS. A later patch tries to remove as many of these TLS lookups
as possible so that performance doesn't suffer.

6df90ba01c Bug 1359245 - Move JS engine promise callbacks from JSRuntime to JSContext (r=till) 
The promise callbacks are intended to run on the XPCJSContext, so the data
that is associated with them should be per-context. We might as well make
the callbacks themselves per-context as well.
