09c489ea93 Re-land: Implement ObservedArrayPop, ObservedArrayShift, ObservedArrayUnshift & ObservedArraySplice 
Original issue: https://codereview.chromium.org/15331002/

Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.

IsObserved now checks for JSReceiver and returns false rather than crashing.

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.

Bug description: in strict mode, null as receiver is not implicitly converted
to the global object, so that when formatting the stack trace, the receiver of
the stack frame is null. The IS_OBJECT check returns true for null, but
%GetDataProperty expected a JSObject, which results in a failed RUNTIME_ASSERT.

36e91242fd Make Object.freeze fast 
This patch both speeds up the freeze operation itself, but also
allows properties to remain in fast mode. Objects with non-empty
elements backing stores still end up with slow elements.

Relanding r14758 and r14759 with fix for Test262: only mark properties
and elements READ_ONLY if they are not JS setter/getters. Tightened up
tests to assert frozen-ness, and added targeted tests for the new code
(covering accessors).

31b8fc19c3 With flag optimize-constructed-arrays on, ARM and MIPS suffered a performance degrade due to incorrect code in GenerateRecordCallTarget(). 
The CL also enables flag optimize-constructed-arrays.

e24cc32011 GeneratorFunction() makes generator instances 
The current specification has GeneratorFunction() be like Function(),
except that it makes generator instances.  This commit implements that
behavior.  It also fills in a piece of the implementation where
otherwise calling GeneratorFunction or GeneratorFunctionPrototype would
cause an abort because they have no code.

d6fa1d8ad9 Function constructor should avoid String.prototype methods 
Replace a use of .indexOf with a call to StringIndexOf.  As always,
lexical scoping to the rescue.

8f602260d3 Implement yield* (delegating yield) 
Ideally this would have been implemented via desugaring at parse-time,
but yield* is an expression, and its desugaring includes statements like
while and try/catch.  We'd have to have BlockExpression in the AST to
support that, and it's not worth it for this feature.

So instead we implement all of the logic in
FullCodeGenerator::VisitYield.  Delegating yield AST nodes now have a
try handler index, for the try/catch.  Otherwise the implementation is
straightforward.
