Add basic infrastructure for reading and writting TBD files (version 1 - 3). The TextAPI library is not used by anything yet (besides the unit tests). Tool support will be added in a separate commit. The TBD format is currently documented in the implementation file (TextStub.cpp). https://reviews.llvm.org/D53945 Update: This contains changes to fix issues discovered by the bots: - add parentheses to silence warnings. - rename variables - use PlatformType from BinaryFormat llvm-svn: 347823
