useless-if-before-free: skip non-matching lines early
* build-aux/useless-if-before-free: First match each line with the
simple/quick /\bif\b/ and reject if there is no match. This often
saves the cost of the much more involved regular expression.
For libvirt, this decreases the cost from 1.44s to 1.02s.
