bc9bc0de1a Fix handle zapping interaction with NoHandleAllocation.
This makes sure that closed handle scopes are properly zapped even if an
enclosing NoHandleAllocation shrunk the limit. It also unifies the code
that performs scope closing for internal and external handle scopes.

515aec2014 Transforming PersistentHandleVisitor to not need to copy Persistent handles.
This gets rid of more places where Persistent handles are copied
(see crbug.com/236290 ).

Transition plan: after this CL, Blink will be modified to work both with and
without the #define, then the #define will be removed from V8.

The corresponding Blink side changes are in https://codereview.chromium.org/15670010/ .

this method can be deprecated and all the code that supports filtering
CPU profiles based on security origins can be later removed.

Drive-by fix: in line with CpuProfiler changes deprecated HeapProfiler::FindHeapSnapshot to reduce v8 API surface. FindHeapSnapshot may well be implemented based on existing GetSnapshotCount/GetSnapshot and it is only used in the tests.

6fda4e4c28 Collect type feedback in separate pass and store it in AST
Notes:

- For now, just adds the missing type info fields to the AST nodes directly.
  I'd like to factor that out more nicely in a follow-up CL.

- All type feedback now is uniformly collected through AST nodes'
  RecordTypeFeedback functions. At some point, this logic should be moved
  out of ast.cc.

- The typing pass currently simulates the exact same conditions under
  which feedback was collected in Hydrogen before. That also should be
  made more generic in the future.

- Type information itself is unchanged. Making it more regular is
  yet more future work.

Some additional cleanups:

- Lifted out nested class ObjectLiteral::Property, to enable forward declaration.
- Moved around some auxiliary enums.

9d3e7e5b81 Fix Object.freeze for objects with mixed accessors and data properties
The bug in the existing code was that it modified the |attributes|
local variable on its way through the loop in CopyUpToAddAttributes.
But that affected any properties updated after an accessor property.
The code now sets up a mask each time and applies that instead of
mutating |attributes|.

3e41834721 Regexp parser: reset flag after scanning ahead for capture groups.
When the regexp pattern parser encounters an unbound reference to a
capturing group, it needs to scan ahead to decide whether it really
is a reference.  The scan advances to the end of the pattern string
and sets has_more_ to false, but fails to reset it to true so that
later on, parsing a character class wrongly fails.
