This is a reland of https://github.com/nodejs/node/pull/3165. The patch abates
the truncation of script filenames in the perf-event output produced by V8.
V8 commits:

Original commit message:
improve perf_basic_prof filename reporting
The buffer used for appending filenames to the string printed to the
perf_basic_prof log was unnecessarily too small. Bump it up to be at least
kUtf8BufferSize.
Truncation of filenames makes it really hard to work with profiles gathered on
Node.js. Because of the way Node.js works, you can have node module dependencies
in deeply nested directories. The last thing you want when investigating a
performance problem is to have script names be truncated.
This patch is a stop-gap. Ideally, I want no truncation of the filename at all
and use a dynamically growing buffer. That would be a larger change, and I
wanted to have a quick fix available that can be back-ported to Node.js LTS
release.

Store buffers separately, and process them together during

Backport 56a0a797f210e04746f2888116365d29a4bb6afc from V8 upstream to
include post-mortem metadata used by mdb_v8 to support V8 4.6.
Original commit message:
Update post-mortem metadata generation
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.

Original commit message:
Add SetAbortOnUncaughtExceptionCallback API
The --abort-on-uncaught-exception command line switch makes
Isolate::Throw abort if the error being thrown cannot be caught by a
try/catch block.
Embedders may want to use other mechanisms than try/catch blocks to
handle uncaught exceptions. For instance, Node.js has "domain" objects
that have error handlers that can handle uncaught exception like
following:
var d = domain.create();
d.on('error', function onError(err) {
console.log('Handling error');
});
d.run(function() {
throw new Error("boom");
});
These error handlers are called by isolates' message listeners.
If --abort-on-uncaught-exception is *not* used, the isolate's
message listener will be called, which will in turn call the domain's
error handler. The process will output 'Handling error' and will exit
successfully (not due to an uncaught exception). This is the behavior
that Node.js users expect.
However, if --abort-on-uncaught-exception is used and when throwing an
error within a domain that has an error handler, the process will abort
and the domain's error handler will not be called. This is not the
behavior that Node.js users expect.
Having a SetAbortOnUncaughtExceptionCallback API allows embedders to
determine when it's not appropriate to abort and instead handle the
exception via the isolate's message listener.
In the example above, Node.js would set a custom callback with
SetAbortOnUncaughtExceptionCallback that would be implemented as
following (the sample code has been simplified to remove what's not
relevant to this change):
bool ShouldAbortOnUncaughtException(Isolate* isolate) {
return !IsDomainActive();
}
Now when --abort-on-uncaught-exception is used, Isolate::Throw would
call that callback and determine that it should not abort if a domain
with an error handler is active. Instead, the isolate's message listener
would be called and the error would be handled by the domain's error
handler.
I believe this can also be useful for other embedders.

Add ScopeInfo constants to post-mortem metadata
mdb_v8, a post-mortem debugging tool for Node.js, allows users to
inspect ScopeInfo structures in order to get more information about
closures.
Currently, it hardcodes the metadata it uses to find this information.
This change allows it to get this metadata from the node binary itself,
and thus to adapt to future changes made to the layout of the ScopeInfo
data structure.

TypedArray accessor detection: consider entire prototype chain
