Bug description:php_strtr_array_prepare_repls does not check allocation results

Description:
------------
In php_strtr_array_prepare_repls() patterns and *allocs are
allocated on the heap, but it is not checked whether that might
have failed, what can lead to OOB writes.

This may not be a problem with the Zend MM, but can be with other
memory managers.

If that also affects PHP 7 (where strtr() had be reimplemented),
has to be checked.
