Since commit f6f4eb0907 (clang-tidy: Add driver mode argument,
2020-01-19) the `clang-tidy` tool rejects the new option:
Unknown command line argument '--driver-mode=g++'.
This is because we are adding the flag before the main compiler
command-line. Encode it with `--extra-arg-before=` so that `clang-tidy`
knows it is supposed to be part of the compiler command.
