0e400515 - [clang-tidy] Skip declarations in system headers in RenamerClangTidyC… (#151772)

[clang-tidy] Skip declarations in system headers in RenamerClangTidyC… (#151772) …heck One typically only wants to perform renaming operations in user code, not in system headers (which are out of the user's control). Let's skip those altogether. This leads to performance improvements in clang-tidy. As a benchmark, I run all checks on a .cpp file that #includes all C++ standard headers.
