f93f8ded96 String:WriteUtf8: Add REPLACE_INVALID_UTF8 option
This patch makes String::WriteUtf8 replace invalid code points (i.e. unmatched
surrogates) with the unicode replacement character when REPLACE_INVALID_UTF8 is
set.  This is done to avoid creating invalid UTF-8 output which can lead to
compatibility issues with software requiring valid UTF-8 inputs (e.g. the
WebSocket protocol requires valid UTF-8 and terminates connections when invalid
UTF-8 is encountered).

7cee52948f Fix stub-invoked setter callback handling.
When invoking a setter callback for a property using
JSObject::SetPropertyWithCallback(),the callback arguments includes
a correct pair of receiver and holder objects.

Such a pair of _possibly different_ arguments (receiver, holder) must
also be supplied when invoking the same setter callback from JITed
code, when the setter is invoked through the StoreCallbackProperty
stub.

An example where this matters are the accessor properties kept on the
global scope of Worker (i.e., properties kept on the global object
itself, and not on its prototype.) Conflating the receiver with the
holder leads to general confusion when attempting to fetch out the
wrapper object.

ExtensionConfiguration is just a simple container for extension names

additional cleanup on the way, e.g. using the null pattern behind our

This is done similar to weak embedded objects in optimized code (r17102). The
reference from optimized code to a cell is treated weakly in marking visitors
if the cell points to a JSObject. After marking we iterate over all cells
embedded in optimized code. If a cell is not marked but its value is marked,
then we revive the cell by marking it. Otherwise, the cell value is dead, so
we mark the code for deoptimization.

1c33a2d840 Templatise type representation
This is to support both heap- and zone-allocated types in the future (the latter not yet implemented).

Also, handlify the type API some more.

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
