This check is guaranteed by the Promise spec and tested by test262
tests. It only has to run for subclasses. This patch adds the check
to the Promise code.

This patch moves the ES2015 Symbol.species feature from staging to
shipping. @@species should be good to ship now that the regression
from fast-path cases in concat, slice and splice have been addressed.

This patch removes Promise functions and methods which are absent
from the ES2015 specification when the --es-staging flag is on.
The patch is being relanded after being reverted due to an
unrelated bug. This version is slightly different as promise_chain
is installed on the context regardless of the flag value, so that
the Promise::Chain API continues to work until it is deprecated.

Many mjsunit tests (as well as the promises-aplus adapter scripts) were
using Object.observe simply for microtask-enqueueing purposes. Replaced
such uses with %EnqueueMicrotask.
