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.

3621a925b2 reg_alloc: Register allocator related constraints belong with the rest of the register allocator 
HostLocToReg64 contained two DEBUG_ASSERTs invloving constraints that
really belonged to the register allocator.

The register allocator prevents allocation of RSP and R15 because those
are reserved for the stack pointer and the state pointer respectively.

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.

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.

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.
