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.

Whenever more rigorous optimizations are attempted (or even basic ones),

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.

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.
