  Hi!

In order to fix this very minor leak, we need a knob to free all
cpp_dirs that were added.
This adds a free_cpp_dirs() to gcc/incpath and needs review from some
global maintainer or maybe libcpp maintainer for this hunk.

Bootstrapped and regtested on x86_64-unknown-linux without regressions.
Ok for tunk?
