In case a checker is registered multiple times as an alias, the emitted warnings are uniqued by the report message. However, it is random which checker name is included in the warning. When processing the output of clang-tidy this behavior caused some problems. So in this commit clang-tidy has been extended with a --duplicate-reports flag which prevents uniquing the warnings and both checker's messages are printed under their name.
