855c654b25 Add LowMemoryNotification to the API on Android platform. 
Android system provides a unique feature that it sends a notification to the
browser in low memory condition, and the browser cleans up cache and frees
resources. Forcing a GC in low memory condition can free DOM objects and also
can shrink the old spaces.

This patch addresses the last comment in

I would prefer to not use the flags to signal that a compacting collection is
requested.

b8a73f0650 Fix uninitialized members. 
Make sure that the DummyScope top level scope used for pre-parsing have all members initialized. The type of this scope is set to global scope as it is a top level scope. Also ensure that the "naked" Scope constructor can only be used by sub-classes of Scope.

The bug of missing initiaalization of members in the DummyScope was found by Valgrind.

4e03645dc4 Analyze functions for assignment to this properties. 
During parsing functions are analyzed for statements of the form this.x = ...;. These assignments are categorized in two types: simple and non simple. The simple ones are where the right hand side is known to be either a constant or an argument to the function. If a function only contains statements of this type the property names are collected and for the simple assignments the index of the argument or the constant value assigned are stored as well.

When the initial map for a function is created and the function consists of only this type of assignemnts the initial map is created with a descriptor array describing these properties which will be known to always exist in an object created from the function.

The information on this property assignments is not collected during pre-parsing so if compiling using pre-parse data these optimization hints are not available.

Next step will be to use the information collected for the simple assignments to generate constructor code which will create and initialize the object from this information without calling the code for the function.

1656dd639a Fix regression caused by the generation of a shift stub during 
snapshot creation in a better way.

Encode whether or not the stub should use sse3 instructions in the
minor key of the stub.  The stubs generated during snapshot creation
will have sse3 disabled, but they will not be found when sse3 is
enabled.  Therefore they will only affect the code generated as part
of the snapshot.

b3f8ce7ce4 Fix regression caused by context creation optimization r2681. 
The issue is that a shift operation is used when creating the
snapshot.  This means that the shift binary operation stub is
generated at snapshot time without sse3 instructions.

The fix is to use division instead.

d87f83c5f8 Fix issue 427: JS tick processor now works out-of-the-box for Chromium on Windows. 
MSVS names '.map' file using only module's name, so both 'a.exe' and 'a.dll' will have 'a.map' file. To distinguish an originating module, we're now checking for image base which is always 00400000 for .exe files, and not 00400000 for .dlls.

Verified that windows-tick-processor can now process logs from Chromium using .map file generated for 'chrome.dll', an that it still works for V8's 'shell.exe'.
