8754289927 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.

badc29f2ea tests/unicorn: Add type aliases to the Unicorn class 
Centralizes all register and vector array definitions to a single set of
aliases, so if these are ever changed, then the rest of the testing code
will follow suit without the need to manually change them.

a665470545 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.

also be used here, avoiding more falling back to the interpreter.
