simd_three_different: Deduplicate common implementations
...
Generally, the only difference between the signed variants and the
unsigned variants is whether or not we use a sign-extension or
zero-extension, so we can simply use common functions to implement both
cases without totally duplicating code twice here.

fuzz_with_unicorn: Move std::vector outside loop in small random block test case

Avoids constructing and destructing the vector repeatedly, we can just
alter the contents of the vector on each iteration instead. Also move
out the std::array instances as well, like with the floating-point test
case and the single random instruction test case.
We can also use the regular form of std::generate and avoid hardcoding
size values twice.
