Call VSQRT directly to avoid the tiniest (1ulp) precision
error that occurs in the system-supplied sqrt on QNX/ARM.

014a86ef8c ES6: Add Object.getOwnPropertySymbols 
http://people.mozilla.org/~jorendorff/es6-draft.html#sec-object.getownpropertysymbols

This allows you to get the symbols used as property keys for an object.

  var object = {};
  var sym = Symbol();
  object[sym] = 42;
  assert(Object.getOwnPropertySymbols(object)[0] === sym);

This is only available with --harmony-symbols

- Make all failures asynchronous, EXCEPT type errors for resolver
- Disallow non-construct call to Promise constructor
- Don't make combinators go through public this.defer

Also, don't bother using IsCallable.

902a05922b Minor Object.observe optimizations 
This patch includes the follow two minor optimizations:

1) When Object.unobserve-ing, instead of deleting from changeObservers, set the index position to null, and null-check when iterating elsewhere
2) Isolate creation of null-proto objects inside a utility function

These former (deleting) was clearly showing up in d8 --prof traces and the later was preventing optimization of containing functions because of non-standard literal. Combined, on MDV construction/teardown benchmark, saves about 10%.

Note that this patch also cleans up retrieving objectInfo inside a utility function.

fc5834343f Remove flag track-allocation-sites. 
The flag has been on in the build for ~9 months, and we aren't likely to turn it off. The only customer of the flag is a set of tests that want to verify transitioning behavior in isolation. This CL removes the flag and updates those tests to get what they want without the flag.

687537ded3 Fix some out-of-line constant pool garbage collection bugs. 
This CL fixes some bugs in the out of line constant pool implementation when
constant pools are GCed.  Namely:
  - Push/Pop pp register in exit frames and VisitPointer on it to ensure it is
    updated if the ConstantPoolArray is moved by GC.
  - Mark pp as a SafePoint Register for optimized functions.
  - Ensure that StandardFrame::IterateExpressions also iterates over the
    constant pool pointer in the stackframe.
  - Fix calculation of last_ptr_offset in ConstantPoolArray body iterator.
  - Make ensure that CONSTANT_POOL_ARRAY_TYPE is a pointer object InstanceType.

0030356cd0 Add better remote control to push-to-trunk auto-roll script. 
This CL enables controlling the automatic push-to-trunk via a settings file .auto-roll in the home directory or via the v8 status app message.

Pushes can be disabled by setting .auto-roll to {"enable_auto_roll": false} or by adding the phrase "nopush" or "no push" to http://v8-status.appspot.com/.

acf24331e3 Fixed Lithium environment generation bug for captured objects (created 
by escape analysis). Added several tests that expose the bug.

Summary:
LCodegen::AddToTranslation assumes that Lithium environments are
generated by depth-first traversal, but LChunkBuilder::CreateEnvironment
was generating them in breadth-first fashion. This fixes the
CreateEnvironment to traverse the captured objects depth-first.

Note:
It might be worth considering representing LEnvironment by a list
with the same order as the serialized translation representation
rather than having two lists with a subtle relationship between
them (and then serialize in a slightly different order again).
