- Initial submit based on version 0.9, which uses Clang 5.0.
- Add llvm-link.patch because openSUSE's libLLVM isn't split up.
- Update mappings in iwyu_include_picker.patch.
- Remove obsolete mapping files.
- Add a manual page derived from the `--help` output.
- Add section about mapping files to the man page.
- Remove x86-specific code that is required to parse Microsoft
inline assembly. We don't need that, and it breaks the builds
on other architectures.
- Add runtime dependency to clang, because we need the compiler-
specific headers, even when clang is not used for compilation.
- Use GCC 6 on SLE 12. For some reason the build using Clang
segfaults, but with GCC 6 it doesn't.
