 We use several `phpversion()` functions in WordPress core, which I propose
 to be replaced with `PHP_VERSION` constants.

 `phpversion()` return value and `PHP_VERSION` constant value are
 identical, but the former is about 3 times slower because it is a function
 call compared to a direct constant value lookup.


 Simple benchmark:

 {{{#!php
 <?php

 $start = microtime(true);
 for ($i = 0; $i < 1000000; $i++) {phpversion();}
 echo microtime(true) - $start;

 echo "\r\n";

 $start = microtime(true);
 for ($i = 0; $i < 1000000; $i++) {PHP_VERSION;}
 echo microtime(true) - $start;
 }}}
