[PHP] When using %throws or %catches, SWIG-generated PHP5 wrappers

now throw PHP Exception objects instead of giving a PHP error of
type E_ERROR.

This change shouldn't cause incompatibility issues, since you can't
set an error handler for E_ERROR, so previously PHP would just exit
which also happens for unhandled exceptions.  The benefit is you can
now catch them if you want to.

Fixes SF#2545578 and SF#2955522.
