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.
