b50114ae70 A64/fuzz_with_unicorn: Avoid repeated unnecessary library calls in RunTestInstance()
Repeatedly retrieving the vectors and registers from unicorn involves
copying the entire set of registers and vectors by value instead of
simply retrieving a reference to them. Instead, we can just do the work
once and print out the values.

While we're at it, also make our bracing consistent.

134bb02e19 ir/value: Replace includes with forward declarations
enum classes are still considered complete types when forward declared
(as the compiler knows the exact size of the type from the declaration
alone). The only difference in this case being that the members of the
enum class aren't visible. Given we don't use the members within this
header in any way, we can simply forward declare them here and remove
the inclusions.

a25bacc436 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.

d909b0919e 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.
