f2bf795876 intrusive_list: Interface changes 
- Remove the root pointer from iterators.

This is unnecessary, since the only way to get a valid iterator is
either from a node itself (it transiently becomes an iterator via the
underlying interface), or through the iterator interface for the list.
This should also result in better code generation, as each increment or
decrement of an iterator is now branchless.

- Remove iterator_to

This is actually a pretty dangerous function, since it would immediately
create an iterator into the list using the given item, even if it's not
actually part of the list. This was only left around due to lack of
type handling around constructors.

- Add other overloads for erase() and remove()

Now handles iterators, pointers, and references.

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.

439619c827 reg_alloc: Make GetRegLoc return by const reference 
Considering a HostLocInfo instance houses a std::vector, every time this
function is called can cause a potential heap allocation.

This can be somewhat unnecessary because this function is only used to query
for information we already have.

Considering this is used by several other internal query functions such as
IsRegisterOccupied, IsRegisterAllocated, and IsLastUse, this will result
in better codegen (returning an address is just 3 instructions excluding
the ret instruction for returning, meanwhile heap alloc can be 60+).

This also renames the function to have the same name as its non-const
counterpart, since overloading will just select the correct function
instead of putting that onus on the developer.
