Add internal fields to JSArrayBufferViews (JSTypedArray and JSDataView)
...
In Blink, JSTypedArray and JSDataView objects act as "wrappers" for C++
objects. Wrapping protocol in Blink requires all wrapper JavaScript objects
to have a certain amount of internal fields that Blink uses for
book-keeping (essentially a pointer to C++ object and some type
information). This change adds those internal fields to JSTypedArray and
JSDataView, in a similiar way to how it is done for JSArrayBuffer.

%CompleteOptimization attempts to install optimized functions
that the parallel thread has put on the output queue, as long as
the function is marked with a builtin. However, activating the
debugger will set all functions to the lazy recompile builtin,
without the function being on the parallel recompilation pipeline.
So we wait for the function to finish parallel recompilation
while it's marked by a builtin that's unrelated to parallel
recompilation.

Generators: Avoid calling into runtime if operand stack is empty
...
This patch makes yield sites save the resume continuation and context
inline. If the operand stack is empty, we can avoid a call into the
runtime. This also makes the SuspendJSGeneratorObject runtime function
less magical: it just has to save the operand stack and stack handlers.
This speeds up the following case by a factor of 3 or so:
function* until(n) {
for (var i = 0; i < n; i++)
yield i;
}
function sum(iter) {
var sum = 0;
for (var x of iter) sum += x;
return sum;
}
for (var i = 0; i < 10000; i++) sum(until(1000))
Also, there is no more sentinel value as the generators will resume in
the right place already, allowing me to remove the hack added to the
--debug-code check in r14437.

Add type field to AST expression nodes
...
More importantly, do a bunch of renamings of incidental existing "types" to avoid actual and potential name clashes (and also to improve consistency).

Move runtime array constructor functions from builtins.cc to runtime.cc.
...
Not only is runtime.cc a better location, but situations arise soon where we'll
want to make runtime calls to these functions.

Deprecate FACTORY helper macro.
...
This removes the FACTORY helper macro to avoid accidental TLS access
when using the factory. Most internal code has access to the Isolate by
now whereas tests which are not performance critical still heavily use
TLS access through explicit Isolate::Current() calls.

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.
