This includes some annotations to isOverridableField() that are only necessary at this point in the patch stack; the entire function will be removed shortly.

GetCurrentPhysicalThread and GetCurrentVirtualThread are, in practice,
identical, as the TLS override that GetCurrentVirtualThread depends on
is never actually set. This simply removes that and renames some things/
deletes some comments.

Defines an android-only version of nsTraceRefcnt::WalkTheStack that takes a function callback, which outputs the stack frame buffer to `__android_log_print`. Also uses `__wrap_dladdr` in MozDescribeCodeAddress, which outputs slightly more informative data for the stack trace (instead of instances of '???/??? [???]').

NS_ERROR_DOM_TYPE_ERR is not much better, but this at least allows us to get
rid of NS_ERROR_TYPE_ERR completely...

In places where profiler_is_active() was used around a profiler_add_marker() (or

mAboutToBeNotifiedRejectedPromises will be clear in AfterProcessMicrotasks()
and mPendingUnhandledRejections will be clear after NotifyUnhandledRejections
runnable is handled.
However, worker could terminate in any time, we still need to clear those
structures manually before CollectData is clear.

This reverts the available memory tracker back to its old implementation that
relied on GlobalMemoryStatusEx() instead of the potentially expensive
K32GetPerformanceInfo(). In spite of its name GlobalMemoryStatusEx() may return
per-process values instead of global ones which might lead to underestimating
the actual memory pressure. Because of this limitation this change is a
stop-gap while we replace this code with a non-polling implementation based on
QueryMemoryResourceNotification().

All calls to `profiler_add_marker()` (outside of the profilers code) are
now replaced by either:
- `PROFILER_ADD_MARKER(name, categoryPair)`
- `PROFILER_ADD_MARKER_WITH_PAYLOAD(name, categoryPair, TypeOfMarkerPayload,
(payload, ..., arguments))`
This makes all calls consistent, and they won't need to prefix the category pair
with `JS::ProfilingCategoryPair::`.
Also it will make it easier to add (and later remove) internal-profiling
instrumentation (bug 1576550), and to replace heap-allocated payloads with
stack-allocated ones (bug 1576555).

Compilers have gotten a lot better since the last time we tried this, and the
generated SIMD code for the inlined memcmp is more efficient than our manual
comparison operations.

Whereas previously MozDescribeCodeAddress would have handled demangling,
we need to explicitly do that from our new GetFunction method. The string we
generate is now more useful for the profiler to merge -- having dropped the
address in the previous patch, and the file & line number and library in this
patch.
While we're at it, try to demangle Rust symbols too.
Ideally we'd add Rust symbol handling to DemangleSymbol in
StackWalk.cpp, but that lives in mozglue, which currently cannot have
any Rust crate dependencies.

This patch adds `RunOnShutdown`, which allows the caller to supply any callable
to be invoked during the specified shutdown phase. This allows us to do more
than just clear smart pointers without needing to write a bunch of observer
service boilerplate.
We use `std::function` to hold the callable.

JSClass contained void* members corresponding to the internal pointer members of js::Class. This stores the internal members in JSClass and removes js::Class.
This leaves js::Class aliased to JSClass while we remove references to it. I also aliased Jsvalify and Valueify into global scope temporarily to make this compile. These get removed in the following patches.
I had to remove a few functions which now don't compile with js::Class being the same type as JSClass.

We always define it to the same thing, and we're inconsistent in whether
we use `CPP_THROW_NEW` or `throw()`, so we might as well just use the
standard C++ thing and get rid of some baggage.

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.
