説明

When https://clang.llvm.org/extra/clang-tidy/checks/llvm/header-guard.html check sees a file with has "llvm" inside its filepath (e.g. clang-tools-extra/clang-tidy/llvm/HeaderGuardCheck.h), instead of making such ifdef:

#ifndef LLVM_CLANG_TOOLS_EXTRA_CLANG_TIDY_LLVM_HEADERGUARDCHECK_H

The check makes:

#ifndef LLVM_HEADERGUARDCHECK_H

The check removes leading part if sees "LLVM" in check-name which is incorrect.
