vegorov@google.com d30ecd3fcd Fix Win64 build of Dart VM.
1. Build script tools/build.py now actually builds X64 target when x64
is passed as an architecture:

- GYP files set 'msvs_configuration_platform': 'x64' for Win_x64
configuration;

- NSS related files are fixed to have correct set of defines for ia32
and x64 builds and include right files. A os_windows.c file added to
work-around inability to have different sets of source files per
configuration. Originally this was controlled through target_arch GYP
define and required regeneration of the solution.

- build.py passes Win32 or x64 platform to devenv as part of build
configuration argument;

2. Dart VM now supports Win64 ABI. ABI description is moved into a
separate class CallingConventions in constants_x64.h.
