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.

basic_block: Add proxy member functions for the instruction list
...
Currently basic block kind of acts like a 'dumb struct' which makes things
a little more verbose to write (as opposed to keeping it all in one place,
I guess). It's also a little wonky conceptually, considering a block is
composed of instructions (i.e. 'contains' them).
So providing accessors that make it act more like a container can make working
with algorithms a little nicer. It also makes the API a little more
defined.
Ideally, the list would be only available through a function, but
currently, the pool allocator is exposed, which seems somewhat odd,
considering the block itself should manage its overall allocations
(with placement new, and regular new), rather than putting that
sanitizing directly on the IR emitter (it should just care about emission,
not block state). However, recontaining that can be followed up with,
as it's very trivial to do.

C++17 introduces non-member empty() which allows for nicer handling

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.
