ClangTidy Test Helper
=====================
This script runs clang-tidy in fix mode and verify fixes, messages or both.
Usage:
check_clang_tidy.py [-resource-dir <resource-dir>] \
<source-file> <check-name> <temp-file> \
-- [optional clang-tidy arguments]
Example:
// RUN: %check_clang_tidy %s llvm-include-order %t -- -- -isystem %S/Inputs
