At some point we will need to either provide a pexpect equivalent on Windows, or provide some other method of doing out-of-process tests. Even with a pexpect replacement, it may be worth re-evaluating some of these tests to see if they would be better served as in-process tests. The larger issue of coming up with a pexpect replacement on Windows is tracked in http://llvm.org/pr22274. llvm-svn: 226614
