unictype/numeric: Fix undefined behaviour.
Reported by Jeffrey Walton <noloader@gmail.com>.
* lib/unictype/numeric.c (uc_numeric_value): Avoid undefined behaviour
on shift overflow, caught by "gcc -fsanitize=undefined".
* lib/unictype/bidi_of.c (uc_bidi_class): Add cast, for clarity.
* lib/unictype/categ_of.c (lookup_withtable): Likewise.
* lib/unictype/joininggroup_of.c (uc_joining_group): Likewise.
