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.
