Introduce t_isalnum() to replace t_isalpha() || t_isdigit() tests.
ts_locale.c omitted support for "isalnum" tests, perhaps on the grounds that there were initially no use-cases for that. However, both ltree and pg_trgm need such tests, and we do also have one use-case now in the core backend. The workaround of testing isalpha and isdigit separately seems quite inefficient, especially when dealing with multibyte characters; so let's fill in the missing support.
