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 - Trying if switching from a vector to an array will appeas the bots. - Replace the tuple with a struct to work around an explicit constructor bug. - This fixes an issue where we were leaking the YAML document if there was a parsing error. Updated the license information in all files. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@356820 91177308-0d34-0410-b5e6-96231b3b80d8
