MDEV-8102 REGEXP function fails to match hex values when expression is stored as a variable
...
We don't fix the bug itself, we just make regex functions display errors
returned from pcre_exec() as MariaDB warnings.

MDEV-4425 Regexp enhancements
...
Do not pass PCRE_UCP flag for binary data.
This makes bytes 0x80..FF not to belong to
generic character classes \d (digit) and \w (word character).
SELECT 0xFF RLIKE '\\w';
-> 0
Note, this change does not affect non-binary data,
which is still examined with the PCRE_UCP flag by default.
