Threads can race to be the first one to calculate the empty path ref's bounds.
To dodge the problem, call computeBounds when creating the global empty path
ref.
There's still another race here, which is that we can race to create the empty
path ref in the first place. As written we can conceivably allocate an
arbitrary number of empty path refs, one of which ends up pointed to by the
global variable at the end.
I've punted on fixing this for now because 1) tsan has not complained yet; 2) I
think it can be fixed by the same approach as we can fix the memsets in
25415003, so I want to wait to see how that review goes
first.
