There is a missing NULL check for: "internal_isolate->context() != NULL".
Right now before calling this method one should call v8::Context::InContext()
first to perform this check, otherwise we may crash. But this static method
will do this check on the current isolate, which may not be the same as a given one.

MIPS: Generators: Avoid calling into runtime if operand stack is empty
...
Port r15240 (909f716e)
Original commit message:
This patch makes yield sites save the resume continuation and context
inline. If the operand stack is empty, we can avoid a call into the
runtime. This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.
This speeds up the following case by a factor of 3 or so:
function* until(n) {
for (var i = 0; i < n; i++)
yield i;
}
function sum(iter) {
var sum = 0;
for (var x of iter) sum += x;
return sum;
}
for (var i = 0; i < 10000; i++) sum(until(1000))
Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

Introduce THREADED_PROFILED_TEST macro
...
A bunch of tests in test-api.cc need to be executed two times: with CPU profiler on and off to check different code paths. There are only two such tests at the moment but I'm going to add more and having this logic duplicated in all these tests look awkward. The tests are executed as part of Threading* tests and there is no much sense in running CPU profiler in that case. This change addresses both problems by introducing THREADED_PROFILED_TEST macro which mosly resembles THREADED_TEST except that when such test is executed as a standalone test (not part of a test-api/Threading*) it will first run the test normally and the start CPU profiler and run the test again.
