This adds the swiftMSVCRT module which is similar in spirit to swiftGlibc and swiftDarwin, exposing the Microsoft C Runtime library to swift. Furthermore, disable pieces of the standard library which are not immediately trivially portable to Windows. A lot of this functionality can still be implemented and exposed to the user, however, this is the quickest means to a PoC for native windows support. As a temporary solution, add a -DCYGWIN flag to indicate that we are building for the cygwin windows target. This allows us to continue supporting the cygwin environment whilst making the windows port work natively against the windows environment (msvc). Eventually, that will hopefully be replaced with an environment check in swift.
