Clang just got more strict about unused lambda captures,
and that requires us to clean all places with this issue
across all the Chromium code base. This CL fixes all such

Right now running the Map and Set builtins with I+TF would tank
seriously because these builtins are still built on top of a
couple of classic intrinsics that TurboFan doesn't understand.
Middle-term the idea is to replace the Map and Set builtins with
a CodeStubAssembler based solution, but for that might not be
ready in time, so adding support for a couple of the critical
intrinsics to mitigate the tankage a bit, namely
- %_JSCollectionGetTable,
- %_TheHole, and
- %_StringGetRawHashField.
Together these double the score on most of the existing performance
tests for collections.

Document that frame summaries are bottom-to-top, i.e. caller before
callee, rename FrameSummary::GetFirst to FrameSummary::GetBottom and
introduce FrameSummary::GetTop.
For debugged JavaScript frames, it does not really matter which of the
functions we call, so I replaced a few GetFirst by GetTop instead of
GetBottom because it matches the semantics more closely.
This CL also reverts part of http://crrev.com/2621953002 by changing
BreakLocation::FromFrame back to accept a DebugInfo and a
JavaScriptFrame. We don't plan to create BreakLocations for wasm.

Instead of doing the dance via JSStrictEqual for comparisons with null,
undefined or the hole, we can just go to ReferenceEqual directly. Also
avoid the Select(x, false, true) dance for negation and use BooleanNot

Intl constructors are specified to prohibit structurally invalid
subtags. BCP 47 defines itself to be case-insensitive. Firefox does
throw on case-insensitive duplicates, following the specifications.
This patch makes V8 do the same. There is some small compatibility
risk, but the case is fairly niche, so I hope it does not cause
much breakage.

The IA32AddPair and IA32SubPair instructions were using an input register as a
temporary value, which led to registers sometimes being clobbered when they
shouldn't have been. This led to problems, for example, in calling printf to
format doubles:
printf("%f", 1.2345) => 0.61725 (on x86)

Inspector is moved to per-event-type callbacks instead of general v8::debug::SetDebugEventListener. It allows to:

- avoid redundant JS call on each event to get properties of event objects,
- introduce better pure C++ API for these events later.

This CL implements ldrex, ldrexb, ldrexh, strex, strexb, and strexh in the
Simulator. These instructions provide "exclusive" access, which provides mutual
exclusion for concurrent threads of execution.
The ARM specification gives some leeway to implementors, but essentially
describes each processor as having Local Monitor and Global Monitor. The Local
Monitor is used to check the exclusivity state without having to synchronize
with other processors. The Global Monitor is shared between processors. We
model both to make it easier to match behavior with the spec.
When running with multiple OS threads, each thread has its own isolate, and
each isolate has its own Simulator. The Local Monitor is stored directly on the
Simulator, and the Global Monitor is stored as a lazy singleton. The Global
Monitor maintains a linked-list of all Simulators.
All loads/stores (even non-exclusive) are guarded by the Global Monitor's mutex.

So far we only recognized
typeof x == 'type'
typeof x != 'type'
typeof x === 'type'
typeof x !== 'type'
but some people seem to prefer it the other way around, i.e.
'type' == typeof x
'type' != typeof x
'type' === typeof x
'type' !== typeof x
as spotted in some Ember.js code, so we should obviously handle that as
well and reduce it to a quick check on x instead of calling the TypeOf
builtin and comparing the resulting string.
