Because ShouldIncludeEdge considers the |origin| node as well, it was possible for
the old code to 'miss' nodes and never write them to the core dump even though we
also wrote some edges with the node as referent.

Mechanical change from Matcher::match(...) to Matcher::operator()(...).
This will now permit the use of generic lambdas, and facilitate the
implementation of multi-lambda match.

For cases where the class has direct calls (that is, we cast `this` to the
subclass before making the call) no longer declare Recv/Answer methods on the
base class at all. This should ensure that slots for them are not generated in
vtables, and also allow the derived class to choose the method signature (e.g.
whether it wants to take something by reference or by value).

When calling a Recv/Alloc/Dealloc method on most types, cast `this` to the
derived class.
There is a heuristic to figure out what the correct derived type is. There is a
blacklist of types which we can't do direct calls on for the moment, as well as
an override for types that do work with direct calls but which don't match the
heuristic.

Bug 1514594: Part 3a - Change ChromeUtils.import to return an exports object; not pollute global. r=mccr8
This changes the behavior of ChromeUtils.import() to return an exports object,
rather than a module global, in all cases except when `null` is passed as a
second argument, and changes the default behavior not to pollute the global
scope with the module's exports. Thus, the following code written for the old
model:
ChromeUtils.import("resource://gre/modules/Services.jsm");
is approximately the same as the following, in the new model:
var {Services} = ChromeUtils.import("resource://gre/modules/Services.jsm");
Since the two behaviors are mutually incompatible, this patch will land with a
scripted rewrite to update all existing callers to use the new model rather
than the old.

This is a best effort attempt at ensuring that the adverse impact of
reformatting the entire tree over the comments would be minimal. I've used a
combination of strategies including disabling of formatting, some manual
formatting and some changes to formatting to work around some clang-format
limitations.

The use of <iframe mozbrowser> in test_saveHeapSnapshot_e10s_01.html has
implicitly depended on the "network.disable.ipc.security" pref set to
false, which is the default for desktop and not applicable for Fennec.
With the new mobile test harness, this pref needs to be set explicitly

Entry storage allocation now occurs on the first lookupForAdd()/put()/putNew().
This removes the need for init() and initialized(), and matches how
PLDHashTable/nsTHashtable work. It also removes the need for init() functions
in a lot of types that are built on top of mozilla::Hash{Map,Set}.
Pros:
- No need for init() calls and subsequent checks.
- No memory allocated for empty tables, which are not that uncommon.
Cons:
- An extra branch in lookup() and lookupForAdd(), but not in put()/putNew(),
because the existing checkOverloaded() can handle it.
Specifics:
- Construction now can take a length parameter.
- init() is removed. Explicit length-setting, when necessary, now occurs in the
constructors.
- initialized() is removed.
- capacity() now returns zero when the entry storage is absent.
- lookupForAdd() is no longer `const`, because it can instantiate the storage,
which requires modifications.
- lookupForAdd() can now return an invalid AddPtr in two cases:
- old: hashing failure (due to OOM in the hasher)
- new: OOM while instantiating entry storage
The existing failure handling paths for the old case work for the new case.
- clear(), finish(), and clearAndShrink() are replaced by clear(), compact(),
and reserve(). The old compactIfUnderloaded() is also removed.
- Capacity computation code is now in its own functions, bestCapacity() and
hashShift(). setTableSizeLog2() is removed.
- uint32_t is used throughout for capacities, instead of size_t, for
consistency with other similar values.
- changeTableSize() now takes a capacity instead of a deltaLog2, and it can now
handle !mTable.
Measurements:
- Total source code size is reduced by over 900 lines. Also, lots of existing
lines got shorter (i.e. two checks were reduced to one).
- Executable size barely changed, down by 2 KiB on Linux64. The extra branches
are compensated for by the lack of init() calls.
- Speed changed negligibly. The instruction count for Bench_Cpp_MozHash
increased from 2.84 billion to 2.89 billion but any execution time change was
well below noise.
Some test files were affected by adding a new CoarseType, particularly in XPCShell tests. New rules were added to handle this CoarseType, and in a few cases the IDs of deserialized nodes had to be adjusted. The colors of CoarseTypes have also changed slightly and the resulting tests had to be updated.

Added a new CoarseType that refers to DOM nodes. Updated the trees to represent the CoarseType. Created a new type of count in the heap snapshot that sorts the data by a more descriptive type name. Created the descriptive in JS::ubi::Base.

This removes AutoMaybeEnterFrameRealm. Most places pass cx->realm->principals: it preserves behavior when the (possibly wrapped) SavedFrame and cx are same-compartment. The main exception is the JSStackFrame DOM bindings code where we have to be a bit smarter about which principals to use.
