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.

b25bb230cd Removed apiutils.h and related cleanup. 
ExtensionConfiguration is just a simple container for extension names
(in a perfect world we would use vector<string> and range-based for
loops), and HandleScopeData was in the totally wrong place. Some
additional cleanup on the way, e.g. using the null pattern behind our
external API.

2638dca48f Make cells pointing to JSObjects weak in optimized code. 
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.

e3e7daf01c We need to know if a load, store or call IC is assumed 
to be on the global object. Previously, this information
was stored in RelocInfo. A more logical place for this kind
of structural information is ExtraICState. Storing it there
makes it easier for us to gather type feedback from these
sites too.

e3fa6d67ca Avoid duplication of a hidden & inherited prototype's properties. 
In Runtime_GetLocalPropertyNames(), the hidden prototypes of an object
are also consulted when deriving the property name set. However, if
given a function object and its template was inherited from the
template of one of its hidden prototypes, that hidden prototype's
property accessors will be present on the object already. Unwanted
duplicates will therefore appear.

Hence, go through the property names that the hidden prototypes
contribute and remove any already occurring ones.

Assumed to be a rare constellation, so the cost of this extra pass is
considered acceptable.
