When descriptor arrays where allocated with the initial map the handling of allocation failures was not correct. This could cause the map returned could possible have been collected.

-fstrict-aliasing is enabled by mainline gcc at -O2 and higher, but in Apple
gcc, it must be enabled explicitly.  This results in a 1.5% improvement in V8
benchmark scores.

This also removes the -fno-exceptions and -fno-rtti settings from v8.gyp for
the Mac, and removes -fno-rtti from v8.gyp for Linux, because these settings
have become part of Chromium's common.gypi, included here, as of r23304 at the
latest.  The settings in v8.gyp have become redundant.

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.

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.

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.

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.

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.
