littledan 88c8361b8f Unstage non-standard Promise functions
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.
