335d162556 [cctest] Bump max old space size for isolate creation
Bump limit for isolate creation in cctest; the test started crashing recently
on nosnap.debug builds, hence we bump the limit.

4da05e97ad [SAB] Fix flake in Atomics.wait
As specified in https://tc39.github.io/ecma262/#sec-atomics-wait, the
critical section must occur before the load and comparison.

This slightly changes the `AtomicsWaitCallback` API, but in a
direction that arguably makes it more consistent.

As a drive-by fix, reset `node->waiting_` in case there
was an exception from the first callback.

5eaa03b2d3 [api] Add AtomicsWaitCallback for diagnostics
Add an inspection callback for embedders that allows tracking
of `Atomics.wait()` calls in order to enable diagnostic tooling
around it, as well as providing a way to break out of an
`Atomics.wait()` call without having to fully terminate execution.

The motivation here is that this allows embedders to perform
somewhat customizable deadlock detection.

70b5fd3b6e [api] Add option to consume code cache on module compilation
This extends the ScriptCompiler::CompileModule function with a
CompileOptions argument. Accepted values are kNoCompileOptions (in
which case, behavior remains unmodified) and kConsumeCodeCache. If the
latter is passed, we try to fetch the given module from the code
cache.

Since it is possible to compile the same source code as both a script
and a module (and different code is generated for the two cases), a
new is_module bit is added to the SerializedCodeData header to
disambiguate between the two cases.

This basically moves the syntactic clutter of having to write

to a central location.

8ec92f5118 [api] Add a dedicated UnboundModuleScript type
Module and script SharedFunctionInfos can't be used interchangeably
(e.g.: it should not be possible to bind a Module's SFI to a Context).

The dedicated type disambiguates the two.

This also adds an overload for CreateCodeCache which takes an unbound
module script instead of an unbound script. Both are just a SFI
underneath, so their behavior is identical.

d8131cd63a [builtins] Convert CEntry/GetProperty/StringAdd stubs to builtins
Stubs and builtins are very similar. The main differences are that
stubs can be parameterized and may be generated at runtime, whereas
builtins are generated at mksnapshot-time and shipped with the snapshot
(or embedded into the binary).

My main motivation for these conversions is that we can generate
faster calls and jumps to (embedded) builtins callees from (embedded)
builtin callers. Instead of going through the builtins constants table
indirection, we can simply do a pc-relative call/jump.

This also unlocks other refactorings, e.g. removal of
CallRuntimeDelayed.

2d3f6f9103 [api] Add Module::GetUnboundScript()
This method is intended for use by code caching as follows:

1. The module is compiled (and perhaps instantiated).
2. The embedder fetches and stores the module's unbound script (i.e.
   the shared function info).
3. Module evaluation, maybe triggering lazy compilation.
4. Generated code for the module (which hangs off the shared function
   info) is inserted into the code cache.

Subsequent module loads can load from the code cache prior to
evaluation.

2459046c1d [ubsan] Change Address typedef to uintptr_t
The "Address" type is V8's general-purpose type for manipulating memory
addresses. Per the C++ spec, pointer arithmetic and pointer comparisons
are undefined behavior except within the same array; since we generally
don't operate within a C++ array, our general-purpose type shouldn't be
a pointer type.

eab5583aa9 [typedarray] Fix GetBuffer for 0-length off-heap typed arrays.
Fixes a crash that happens when calling postMessage on an empty typed
array.

GetBuffer should only call MaterializeArrayBuffer for on-heap buffers,
but the on-heap check is slightly wrong. This CL moves the on-heap check
logic to the JSTypedArray class so that other parts of the codebase
don't need to worry about how that is determined.

Also add some dchecks to materialize itself. It should only receive
on-heap buffers and should always transform them to off-heap buffers.
There is also no reason for it to be static, so change that here too.

7b29fe434d Rename Code::instruction_{start,end,size} functions
In order to clarify the difference between, e.g., InstructionStart and
instruction_start, rename as follows:

Code::instruction_start -> raw_instruction_start
Code::instruction_end   -> raw_instruction_end
Code::instruction_size  -> raw_instruction_size

The difference between the camel-case and raw_* function families is
in how they handle off-heap-trampoline Code objects. For example, when
called on an off-heap-trampoline: raw_instruction_start returns the
trampoline's entry point, while InstructionStart returns the off-heap
code's entry point (located in the .text section of the binary).

Some callsites were updated to call the camel-case function family as
appropriate.

13ca9a0fd1 [turbofan] Properly optimize calls to promise extras.
Add TurboFan inlining support for the following V8 Extras:

 - v8.createPromise
 - v8.rejectPromise
 - v8.resolvePromise

These are used by the streams implementation in Chrome currently, and
were previously not inlined into TurboFan, although TurboFan already
had all the necessary functionality (namely the JSCreatePromise,
JSRejectPromise and JSResolvePromise operators). We might eventually
want to use these functions in Node core as well (at least short-term
for Node 10), to replace the C++ internal API functions with the same
name that are currently being used by parts of Node core.

For this to work, the rejectPromise and resolvePromise builtins had
to be moved back to CSA, as for JavaScript builtins we still have the
policy that the optimizing compiler must not inline them. But that's
straight-forward since the CSA has all the necessary functionality
available anyways.

1f8dcc5d2e [builtins] Optimize PromiseResolveThenableJob for the common case.
The idea here is that in case the `thenable` is a JSPromise and `then`
is the initial `Promise.prototype.then` method, and the @@species lookup
chain is intact, we can skip creating the temporary promise and the
closures (with the shared context), and instead directly call into our
PerformPromiseThen. This is sound since - given above mentioned
conditions - our short-cut

  PerformPromiseThen(thenable, undefined, undefined, promise_to_resolve)

is not observably different from the actual

  resolve, reject = CreateResolvingFunctions(promise_to_resolve)
  result_capability = NewPromiseCapability(%Promise%)
  PerformPromiseThen(thenable, resolve, reject, result_capability)

except through PromiseHooks (and potentially via the async stack
traces). So we disable the fast-path if either promise hooks are enabled
or the debugger is active for now.

This improves the performance on the wikipedia benchmark by 20-25% and
the bluebird-doxbee benchmark by around 20%.

6004c53da3 [wasm][streaming] Change the signature of the Abort API function to MaybeLocal
When streaming compilation for WebAssembly gets aborted, we reject the
promise associated with the compilation. However, in some circumstances,
e.g. when streaming comilation gets aborted because the browser tab gets
refreshed, then we want to omit rejecting the promise. In an older CL
(https://crrev.com/c/876103) we omit rejecting the promise when the
exception value is null. With this CL the exception value is a MaybeLocal
so that we document properly that the value can be null. In addition, I
added documentation to say that in that case we do not reject the promise.

Blink get's highly confused when we change the "entered or
microtask context" for MicrotaskCallbacks.

ff05633408 [api] Don't mark as constructible if instance_call_handler is used
This only affects document.all, which is the only user of
|ObjectTemplate::SetCallAsFunctionHandler|, and will mean that
new document.all() will throw TypeError. There are tests for this:
//src/third_party/WebKit/LayoutTests/external/wpt/html/infrastructure/common-dom-interfaces/collections/htmlallcollection.html

(cherry picked from commit 7233447e4ac4587c81e91077857f8a30c4a6d2df)

5b9adade64 [proxy] Set [[ProxyTarget]] to null during revocation
Before this, only the [[ProxyHandler]] was set to null during revocation
of the Proxy through either the v8::Proxy::Revoke() or the
Proxy.revocable() API. To be consistent with the spec, the Proxy's
target is set to null as well. This change should not be observable
through JS, since the check for if the Proxy is revoked should always
use the handler. But the changed value is exposed through the public
v8::Proxy::GetTarget() API, which is used by the inspector API and
Node.js.

Also included is a much more comprehensive test for Inspector's support
for Proxy, which prior to this commit did not work as intended.
