This patch exposes a new flag perf_basic_prof_only_functions (disabled by
default) that can be useful for the use-case of running always-on profiling on
long running production jobs.
Original commit

New flag --perf_basic_prof_only_functions
Restricts linux perf-event code range reporting to functions only (i.e. on
stubs.) While this makes the gathered ticks less accurate, it reduces the
growth of the /tmp/perf-${pid}.map file.

Stop profiler on isolate teardown if still running
If the profiler is started via the API and not stopped, V8 will
intermittently crash during isolate teardown.
The fix is to run the DeleteAllProfiles function in Isolate::Deinit()
if cpu_profiler_ still exists.

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: 03ef3cd004
Reland: 010897c16a
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.

Backport 1ee712ab8687e5f4dec93d45da068d37d28feb8b from V8 upstream.
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.

Currently, it hardcodes the metadata it uses to find this information.
