Reviewers: Toon Verwaest,
Description:
Object.observe: generate change records for named properties.
In more detail:
- Set observation bit for observed objects (and make NormalizedMapCache
respect
it).
- Mutation of observed objects is always delegated from ICs to runtime.
- Introduce JS runtime function for notifying generated changes.
- Invoke this function in the appropriate places (including some local
refactoring).
- Inclusion of oldValue field is not yet implemented, nor element
properties.
Also, shortened flag to --harmony-observation.
Object.observe: implement map bit and functions to access it.
