test directory writable

I see filereadable() and filewritable() but I don't see how to do that
with a directory. My problem is that our vimrc specifies a swpfile
directory which is fine for users created with skel, but if it's not
present (for root or users not created with skel) I'd like it to not
error and require :w! and the like to function.
