An earlier commit introduced pathspec_tries, but we did not
actually generate them by default. This patch causes us to
do so when it is possible (i.e., when no wildcards or other
pathspec magic are in use). This doesn't actually do
anything yet, though, as none of the pathspec users have
learned to make use of the tries.
We embed the pathspec_trie directly inside the "struct
pathspec". This is not strictly necessary, as once created,
the trie does not depend on the original pathspec. However,
since the intended use is to optimize existing pathspec
callers, passing the trie around as part of the pathspec
will minimize disruption to the call chain.
