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.
