When introducing experimental extras I forgot to update this check. That resulted in experimental extras running through the steps normally reserved for non-extra natives: macro and constant expansion, validation, and minification. This causes problems since per the linked bug minification is buggy.

This moves JavaScript source files that are bundled with V8 into a
separate directory. The goal is to improve code readability and also
being able to formalize ideal reviewers by subsequently adding the
OWNERS file. These files almost exclusively contain implementations
of methods fully specified by ES6.
Note that files in the "debug" directory as well as the "d8.js" file
aren't affected by this change.

This separates the core machinery and the heuristics involved with
inlining functions calls. So far the heuristic only respects our
%SetForceInlineFlag hint, but it will the place where general inlining
heuristics can live without impeding clarity of the core machinery.

Introduce a new JSGlobalSpecialization advanced reducer that runs
during the initial inlining and context specialization, and specializes
the graph to the globals of the native context. Currently we assume
that we do not inline cross native context, but long-term we will grab
the global object from the JSLoadGlobal/JSStoreGlobal feedback (with the
new global load/store ICs that are currently in the workings), and then
this whole specialization will be fully compositional even across
cross-context inlining.
Note that we cannot really handle most of the stores to global object
property cells because TurboFan doesn't have a mechanism to enforce
certain representations. Also note that we cannot yet fully benefit
from the type feedback collected on the global object property cells,
because the type system cannot deal with maps in a reasonable way.

This adds the unittests to the "default" test set. Now that
the "default" and the DEFAULT_TESTS (i.e. runner with
no arguments) are the same, removed DEFAULT_TESTS and use
TEST_MAP["default"] instead.
On the bots, where unittests and default were run in
separation before, the explicit unittests step should now
be skipped.
This is necessary for swarming, as the unittests step is
too small to justify its own swarming job.

Previous to this patch, both the lithium and TurboFan register
allocators tracked allocated registers by "indices", rather than
the register codes used elsewhere in the runtime. This patch
ensures that codes are used everywhere, and in the process cleans
up a bunch of redundant code and adds more structure to how the
set of allocatable registers is defined.
Some highlights of changes:
* TurboFan's RegisterConfiguration class moved to V8's top level
so that it can be shared with Crankshaft.
* Various "ToAllocationIndex" and related methods removed.
* Code that can be easily shared between Register classes on
different platforms is now shared.
* The list of allocatable registers on each platform is declared
as a list rather than implicitly via the register index <->
code mapping.

we get otherwise).

Also fixes a bug with ToBoolean where it wouldn't get emitted at the start

mdb_v8, a post-mortem debugger for Node.js, now uses JSArrayBuffer's
backing_store property and JSArrayBufferView's byte_offset property to
get access to the content of Buffer instances in node (which are
Uint8Array instances). This change adds post-mortem metadata for these
two properties.
This change also fixes a typo in
inobject_properties_of_constructor_function_index_offset that was added
to gen-postmortem-metadata in a previous change. It should be named
inobject_properties_or_constructor_function_index instead.
