Comment (by gitlost):

 This patch incorporates the suggestion of @markoheijnen to introduce a
 `_wp_can_use_pcre_u`-like function. It doesn't bother with the
 `\p{Inherited}` change, as it complicates the UCP case, which (as hinted
 at by markoheijnen in [https://wordpress.slack.com/archives/core-
 images/p1474169202000431 Slack]) is undoubtedly the "high-runner" by a
 country mile. The unit test has been expanded to include all Unicode 5.0.0
 Mn characters.
