2.7.6

some miscellaneous speedups and size slims

2.7.3

avoid caching the empty array Promise.all can return as that is mutable.

2.7.2

Some optimization including

• if resolve is given a promise simply return it
• cache the special values that all can return
• upgrade immediate to 2.7.1 which fixes a problem that can cause performance to plummet when lots of promises are being used.

2.7.0

Removed the Promise.prototype.resolve and Promise.prototype.reject methods as they shouldn't have been public, upgraded immediate the the proper microtask version, and some reorganization of the code to be more clear.
