Prevent Undefined Behavior in shift of signed integer in grep(1)
There is an interface in grep: dfa.c with functions to test bit, set bit,
clear bit etc. They operate over the INT-wide mask (INTBITS). Use unsigned
shift in these interfaces to prevent UB.
Detected with MKSANITIZER with the undefined behavior sanitizer option.
