ASCII lower case for zend_operators.c functions

For consistency with the previous change, also use ASCII lower case for
zend_binary_zval_strcasecmp, zend_binary_zval_strncasecmp,
string_compare_function_ex and string_case_compare_function. Only the _l
suffixed functions remain locale-sensitive. I added the consequent
effects to the RFC. The main reason for doing it is so that
array_change_key_case() will be consistent with strtolower().
