[PATCH] D15528: Teach clang-tidy how to -Werror checks.

Thank you for explaining. The use case seems to be important enough to support it. And the solution seems to be good for now. A few concerns:

1. `Werrors` isn't a good name for this. The only reason why a similar thing is called `-Werror` in compilers is that they use `-W` for warnings. I'd suggest TreatAsErrors, WarningsAsErrors or anything similar (with the proper casing change for the command line argument).
2. Documentation is missing.
