66d13be5f9 Fix incorrect encoding of single and double precision registers for some VFP instructions. Also fix incorrect disassembling of vldr/vstr. This is a commit of http://codereview.chromium.org/3107027 for Rodolph Perfetta.

6d5451d685 Add inlining of binary smi operations in the full codegens on IA32 
and x64 (on IA32 we even fold constants into the instructions for
a more compact representation) and prepare the ARM full codegen for
the doing the same there.

7672338bc9 Fixes bug in Object.freeze and Object.seal causing them to misbehave when Array.prototype has changed. 
Object.freeze and Object.seal uses GetOwnPropertyNames which
returns an array with local property names. This array will also have
the additional properties defined on Array.prototype or
Object.prototype.

Note that, the implementation of GetOwnPropertyNames (when used as
Object.getOwnPropertyNames) is correct, since the spec says to create
a new Array (which would also have these properties).

9f65b1e32d Explicitly set expected number of properties for instances of builtin types. 
We used to inherit an estimate on the expected number of properties in
%SetCode. It is not accurate and does not help for the types where
adding custom properties is rare (String, Date, etc.).

6bd9d953dd Reapplying r5147 (caching maps for slow case objects). 
r5147 wrongly assumed that a code cache for a slow case map is always empty.
This patch solves this: whenever we attempt to add a stub to a map's code cache 
we check that this map is cached. If it is we give the object its own copy
of the map and only then modify the map.

b1e27e2cd5 Created collector class and used it to collect identifiers during scanning. 
The collector class automatically expands to hold the values added to it,
like a List, but doesn't ensure that the backing store is contiguous, which
allows it to avoid copying back and forth as the buffer grows.

This is in preparation for identifyng identical symbols during preparsing.
