4d44474ad4 Implemented the ARM UHADD8 instruction. (#45) 
The x64 implementation uses the SSSE3 instruction PSHUFB.
A non-SSE fallback is provided in case the CPU doesn't support it.

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.

d5805cc6eb intrusive_list: Add size querying 
Since we store pointers and have an interface for iterators
set up, the count is just the distance from the beginning
to the end of the list.

Nice thing is that because of this, basic blocks also get
the ability to have a size count without needing to do anything
directly.

1abe881921 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.

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.
