tests: Generate random values in unsigned integer space

Browse source

When we're doing bitwise operations, addition with wraparound and
large left-shifts, it seems safer to use unsigned integers, where
the effect of overflow is well-defined (it wraps around). Signed
integer overflow is undefined behaviour, so compilers are free to
optimize by assuming that it cannot happen.

Detected by the undefined behaviour sanitizer (UBSan).
