This CL removes code that is now unused since the port of regexp.js has been
completed. Removed functions / classes are:
* regexp.js (GetSubstitution moved to string.js)
* RegExpConstructResult stub
* RegExpFlags intrinsic
* RegExpSource intrinsic
* RegExpInitializeAndCompile runtime function

- RegExp.prototype.toString() doesn't have any special handling of
RegExp instances and simply calls the source and flags getters
- Use the original values of global and sticky, rather than based
on the current flag getters, as specified in

Both of them shipped in Chrome 49 without incident.
Also move relevant tests from harmony/ to es6/.

This patch switches TypedArrays to use the prototype chain described
in the ES2015 specification, which adds a %TypedArray% superclass above
all individual TypedArray types. Most methods are defined on the
superclass rather than the subclasses.
In order to prevent a performance regression, a few methods are
marked as inline. Inlining might prevent code which was previously
monomorphic from becoming polymorphic, and it was specifically
applied in places where methods became more polymorphic than before.
Tests with realistic workloads would be nice to do before this
ships in stable.
This patch does not bring TypedArrays up to full spec compliance. In
particular, @@species is not yet supported.

Function subclasses did not have function properties installed (name, prototype, etc.).
Now when an instance of a Function subclass is created it gets initial map that corresponds
to the language mode of the function body. The language mode dependent maps are cached as
special transitions on initial map of the subclass constructor.

1) The Map::CopyInitialMap() did not set descriptor's array if
the source initial map had one.
2) Subclasses are temporarily disallowed to have more in-object
properties than the parent class (for GC reasons).
