Subject: [PATCH 1/2] [clang-tidy] add option to avoid "no checks enabled"
error
When clang-tidy get an empty checks, it will throw "no checks enabled" error
and exit with non-zero return value.
It make clang-tidy's wrapper program confused when in big project some files
don't want to be checked and use `-checks=-*` to disable all checks.
