If directories are passed to gen_compile_commands.py, os.walk() traverses
all the subdirectories to search for .cmd files, but we know some of them
are not worth traversing.
Use the 'topdown' parameter of os.walk to prune them.
Documentation about the 'topdown' option of os.walk:
When topdown is True, the caller can modify the dirnames list
in-place (perhaps using del or slice assignment), and walk() will
only recurse into the subdirectories whose names remain in dirnames;
this can be used to prune the search, impose a specific order of
visiting, or even to inform walk() about directories the caller
creates or renames before it resumes walk() again. Modifying
dirnames when topdown is False has no effect on the behavior of
the walk, because in bottom-up mode the directories in dirnames
are generated before dirpath itself is generated.
This commit prunes four directories, .git, Documentation, include, and
tools.
The first three do not contain any C files, so skipping them makes this
script work slightly faster. My main motivation is the last one, tools/
directory.
