The change https://codereview.chromium.org/1274453002 is causing a breakage
on the Chrome OS builds. It is not clear how to easily revert because there is
a following on dependent change (https://codereview.chromium.org/1351983002) am
I am not too familiar with the revert process.

The simplest revert is to remove the DCHECK.

The internal ConvertToString helper was using the wrong ToPrimitive,
actually the old ES5 like DefaultString, and it also prematurely
optimized for no real benefit.

Also support %_ToString in Crankshaft utilizing the ToStringStub, which
is also used in TurboFan and fullcodegen. This is necessary to repair a
regression on Octane that was introduced when switching from the hand
crafted NonStringToString/ToString magic to %_ToString (which properly
supports @@toPrimitive).

Reverting, because of broken GC stress bots.

@cbruni: Sorry for the revert. I'm not entirely sure it's actually your CL; but policy is to revert speculatively if we can't determine an exact cause.

Not resetting the allocation area after freeing it potentially results in
negative SizeOfObjects() because the area is accounted for as allocated while it

Verifies consistency of node inputs and uses:
- node inputs should agree with the input count computed from the node's operator.
- effect inputs should have effect outputs (or be a sentinel).
- control inputs should have control outputs (or be a sentinel).
- frame state inputs should be frame states (or be a sentinel).
- if the node has control uses, it should produce control.
- if the node has effect uses, it should produce effect.
- if the node has frame state uses, it must be a frame state.

I also removed some tests, either because they did not seem to be useful (scheduler) or they tested dead functionality (diamond effect phi).

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.

The actual Function.prototype.toMethod was removed some time already,
but there were some stuff (esp. %ToMethod) left in the tree, including
tests for %ToMethod.  This code (and esp. the tests) cause trouble in
the process of moving bound functions away from JSFunction; so since
the code is unused anyway, we can as well remove it.

The original removal of Function.prototype.toMethod was in February
2015 in 68e48975.

Since https://codereview.chromium.org/366103005 the promise tests null out
various globals, to ensure the promise implementation doesn’t itself rely
on functions patchable by monkeys.

Unfortunately, doing so breaks test assertion failures which rely on
those globals.

This isn’t the ideal solution, but does improve the current state.
