Update some support builtin classes, constants, and functions to PHP 5.5.9

Updated usiing php reflection whereas the Textmate php bundle uses the
documentation to extract support information to build regexes.

See https://github.com/textmate/php.tmbundle/blob/d24593d75c3c5f01b4b0705a9e6db132c0cfd55b/Support/generate/generate.php

So, not all support regexes could be updated using relfection, because the
reflection extension names don't match how they are documented.

For example, all the string functions are in the relfection extension named
"standard" which includes other functions, whereas in the docs all the string
functions are group named the "string" extension.
