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.

The debugger calls PromiseHasUserDefinedRejectHandler to recursively search the
tree of dependent promises for user-defined reject handlers. If no such reject
handler exists, rejecting the promise is considered an uncaught exception.
Promise.race and Promise.all interupt the link of promise dependency wrt the
search. This change fixes that link.

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.
