ompiler: MSVC related fixes and `v test v` for windows testing

* MSVC related fixes and v test v for windows testing

* If second stage crashes on windows goto error

* use os.exec instead of system so that the error can be printed

* use -debug for osx vid

* Fix some whitespace to trigger a rebuild
