Hrm, on a whim, I tried running the testcase with -no-aa -load-vn -gcse, showing
that alias analysis is taking a trivial amount of time < 1s, so the
"infrastructure problem" that I blamed for the slow GCSE is not really the problem.

Instead, it looks like load-vn is just being really silly, and needs to be
fixed.  *sigh*
