Summary: Split ReaderWriter.h which contains the APIs into both the BitReader and BitWriter libraries into BitcodeReader.h and BitcodeWriter.h. This is to address Chandler's concern about sharing the same API header between multiple libraries (BitReader and BitWriter). That concern is why we create a single bitcode library in our downstream build of clang, which led to r286297 being reverted as it added a dependency that created a cycle only when there is a single bitcode library (not two as in upstream).
