Currently allocation in generated code on ARM is only used for allocating heap numbers. This change factors this out for use in upcomming changes.

This only wins us around 1% in performance, but it makes the code more
compact.  We don't currently have a way to represent in the virtual
frame that a slot contains a value from the root array.  Adding this
would probably make the code more compact.

Make a copy of the descriptor array when copying a map with pre-allocated properties. The garbage collector assumes that no two maps point to the same descriptor array.

A simple reduction is missing.

The SCons build now supports building for 64-bit Windows. This still requires that the SCons build is passed an env parameter containing the PATH and LIB for the 64-bit build as SCons autodetects the 32-bit environment.

Lowered the warning level for the 64-bit build temporarily.

Added a verbose option to SCons to display the startup banner for the Microsoft Visual C++ tools.

Factored out the allocation in new space from assembler code into the macro assembler. To support the current allocation patterns a number of different functions where required.

This is change is identical to http://codereview.chromium.org/174524 (committed in r2768 and reverted in r2769) except that line 710 in macro-assembler-ia32.cc is

  cmp(result_end, Operand::StaticVariable(new_space_allocation_limit));

instead of

  cmp(result, Operand::StaticVariable(new_space_allocation_limit));

and pre-submit fixes as well.

For objects which only have simple assignments of the form this.x = ...; a
specialized constructor stub is now generated. This generated code allocates the
object and fills in the initial properties directly. If this fails for some
reason code continues in the generic constructor stub which in turn might pass
control to the runtime system.

Added counter to see how many objects are constructed using a specialized stub.

The specialized stub is only implemented for ia32 architecture in this change.
For x64 and ARM the generic construct stub is used.

This is change is identical to http://codereview.chromium.org/174392 (committed in r2753 and reverted in r2754) except that a few parts have already been committed from http://codereview.chromium.org/173469 (committed in r2762).

When copying a map always set the descriptor array to describe the pre-allocated properties, even when descriptors are to be dropped.

Added a test which otherwise failed with an assert on ARM in debug mode. The reason for it only surfasing on ARM is that the NewObject runtime function is always used for allocating new JSObjects on ARM.

This change includes a few parts of http://codereview.chromium.org/174392 needed to trigger the error.
