  The FP parameters for X87 should be put in stack and the FP return value
  should be put in stX_0 register.

  So this CL defines the FP_RETURN_REGISTERS as stX_0 only.

Almost all of the Date builtins always call into C++ at least once
anyway, so parsing, compiling and executing the JavaScript wrappers
is just a waste of time.  The most important part here is the Date
constructor itself, which is one of the blockers for new.target in
TurboFan, because compiling the Date constructor takes too much time
with TurboFan (for no reason since we end up in C++ anway).

The mode requires an extra register, and since we aren't supporting

In the Date constructor or Date.parse, other browsers will accept time
zones like GMT-8, but before this patch, Chrome would interpret 8 as
8 minutes. This patch interprets GMT-+ a one or two digit number as hours,

1. Location names with more than one underscores (e.g. Ho_Chi_Minh)
   didn't work because of the way capturing works with repeated patterns
   in RE. It's now supported by changing the RE to capture the whole string
   and splitting on '_' in the next step.

2. Adds support for location names with a hyphen

3. Adds support for timezone ids with three parts (e.g.
   American/Argentina/Buenos_Aires)

4. Adds special handling of 'au', 'es' and 'of' in zone ids. They need to be kept in lowercase. (see the full list at https://en.wikipedia.org/wiki/List_of_tz_database_time_zones )

5. Adds regression tests for all the above and make the existing tests
   more robust against future ICU changes. ICU canonicalizes zone names to
   deprecated names, but it may change. (

This patch adds the basis for subclassing TypedArrays, Arrays and
ArrayBuffers through the @@species hook, added in ES2015. This is
the first patch in a series. This patch simply defines the
@@species Symbol and installs it on the appropriate constructors.
The behavior is guarded behind the --harmony-species flag.

This restricts turbofan to turbofan-supported subset for the shipping
configuration ("use asm" and features unsupported by Crankshaft).

Without this, we compile with Turbofan even when there is
try-catch-finally as long as the function is "use asm" or
it contains a feature unsupported by crankshaft but supported
by turbofan (e.g., 'with' statement).

Use the same mechanism that is already available for Crankshaft to not

We choose to deliberately violate the ES2015 specification and
implement the ArrayBuffer constructor in a way that matches
Firefox and Safari instead.
