9977a2caf3 [elements] update Dictionary in IncludesValue if own elements change 
Ensure that receiver->elements() == *dictionary after calling an accessor, in
addition to checking the prototype.

0d7f7dc3ee [elements] limit TypedElementsAccessor::IncludesValue to backing store length 
The contract is that the method is only invoked when there are no elements on
the prototype, and this elements type forbids accessor elements. So it is safe
to limit the search to the end of the backing store.

c4ee3d9474 [builtins] fix mapcheck in Array.includes fast-case when searching for String 
Use LoadInstanceType() rather than LoadMapInstanceType(), as this part of the

1350eb3dc9 [es8] More spec compliant syntactic tail calls implementation. 
Unlike previous implementation where the 'continue' keyword was a feature of a return statement the keyword is now recognized as a part of expression. Error reporting was significantly improved.

--harmony-explicit-tailcalls option is now orthogonal to --harmony-tailcalls so we can test both modes at the same time.

This CL also adds %GetExceptionDetails(exception) that fetches hidden |start_pos| and |end_pos| values from the exception object.

f6cd009efd ES6: Make function name configurable 
Function name property is now standardized in ES6. It was a Mozilla proprietary
extension before. With ES6, the property was made configurable, so that it can
be used instead of another proprietary property, displayName.

This is a revert of revert c791d84112.

Last time this broke a Chrome browser test which has since been updated:

Temporarily reverting until we figure out how to handle the API cases that use accessors to lazily compute values.
dataAttributeGetterCustom in V8MessageEventCustom (at least) overwrites itself with the computed value using ForceSet. We can either force such clients to first use ForceDelete before caching, use some other caching mechanism; or provide an API for lazily computed properties.

1b270ef5ea Re-enable Object.observe and add enforcement for security invariants. 
This patch reverts r21062 which disabled Object.observe and the relevant tests.

It also adds enforcement for the following three invariants:

1) No observer may receive a change record describing changes to an object which is in different security origin (context have differing security tokens)

2) No observer may receive a change record whose context's security token is different from that of the object described by the change.

3) Object.getNotifier will return null if the caller and the provided object are in differing security origins

Further, it ensures that the global object can never be observed nor a notifier retrieved for it.

Tests are included.

8bd05193c7 Reland "Enable Object.observe by default" again 
This re-re-re-lands enabling Object.observe. The Chromium tests that
failed last time this was rolled into Chromium have been disabled in
https://src.chromium.org/viewvc/chrome?view=revision&revision=256706

This patch should be safe to merge once that lands.
