OK - it didn't increase the time very much either. Without the influence of D122145 <https://reviews.llvm.org/D122145>, these are the compile times I measured. The first column is this patch (almost no change). The second is increasing the limit from 12 to 14.

Increasing the limit is still very small, but a little bigger in places than this patch (and may have worse performance in some degenerate cases).
