These should hopefully all be uncontroversial, minimal changes to deal with progressing the build to completion on OpenBSD or addressing minor portability issues. This is not the full set of changes to get a successful build; other portability issues will be addressed in future commits. Most of this is just adding the relevant clauses to the ifdefs, but of note in this commit: * StdlibUnittest.swift: the default conditional in _getOSVersion assumes an Apple platform, therefore the explicit conditional and the relevant enums need filling out. The default conditional should be #error, but we'll fix this in a different commit. * tgmath.swift.gyb: inexplicably, OpenBSD is missing just lgammal_r. Tests are updated correspondingly. * ThreadLocalStorage.h: we use the pthread implementation, so it seems we should typedef __swift_thread_key_t as pthread_key_t. However, that's also a tweak for another commit.
