55eaa16615 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT 
Discovered by @Subv.
Fixes incomplete fix begun in 5a91c94dca47c9702dee20fbd5ae1f4c07eef9df.
That fix fails to take into account that LinkBlock doesn't update ticks until there
are no remaining ticks to be executed.

Test added to confirm fix.

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.

7a8dd9532d skyeye: Read-after-write in SMLA 
In the case when RD === RN, RD was updated before AddOverflow was called
to check for an overflow, resulting in an incorrect state of the Q flag.

This is reapplying a patch from f12578b9ab
that was lost during the 20e253ece2 update

4acc481463 translate_arm/load_store: Handle unpredictable instructions 
This necessated handling literal versions of the instructions separately
as they had different requirements. The rationale for detecting
unpredictable instructions is because:

a. they are unlikely to be outputted by a well-behaved compiler
b. their behaviour may change between different processors

I would rather unpredictable instructions fail loudly than silently do
approximately the right thing.
