fschneider@google.com 6632f191c4 Support for unboxed 64-bit integer bitwise operations and equality on ia32. 
This CL adds AND, OR, XOR and == operations on unboxed 64-bit integers
(aka. mints).

Unboxed mints are stored in xmm registers. Each xmm register location
has an additional bit to keep track of its value representation.

Unboxed mints are materialized on the heap on deoptmization in the same way as
unboxed doubles.

The SSE instructions used are available on all CPUs that support SSE 4.1.

sgjesse@google.com bf67f24098 Move assert.h/assert.cc from runtime/vm to runtime/platform 
The purpose of this change is twofold:

1. Source in the bin directory can now use the same assertions as
   source in the vm directory. The ASSERT macro used by the code
   in runtime/bin was just defined to use assert from the standard
   C library.
2. Moving other implementation parts from runtime/vm to
   runtime/platform (e.g. classes Monitor and Mutex) for sharing
   between runtime/bin and runtime/vm will be easier as these
   implementations rely on these assertion macros.

Created two gypi files for the platform directory. One for the
headers and one for the source. The source one is only included
when building the VM library and will be present in libdart.a
when the dart executable is linked.

All the code for asserts is still in the dart namespace.

Also re-arranged the order of includes to be alphabetically in
the files touched.
