d589c63107 Implemented the ARM SEL instruction, with tests. (#39) 
The test for this instruction is very peculiar. As the instruction's behavior depends on the value of the CPSR, we generate a MSR instruction after each SEL instruction to change the CPSR.

6d53bb6d7e arm_types: Split out LocationDescriptor (#20) 
This isn't really an ARM-specific type, since it's used to indicate a
Block location.

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.
