There is now no longer a need to call DecrementRemainingUses on the parent
instruction.

54d051977f emit_x64: Use movdqa instead of movaps in EmitPackedSubU8 
While movaps and movdqa are behaviourly equivalent, using movaps may incur
a domain crossing penalty on some microarchitectures. This is because
movaps is an instruction in the floating-point domain while the following
instructions are in the integer domain.

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.
