18f11972c6 emit_x64: Remove SSSE3 implementation of PackedHalvingAddU8
It is much slower than the SSE2 implementation, so there's no point keeping it around.

814e378249 VCMP and VCMPE were the other way around
- This was due to a misunderstanding of what the E in VCMPE means.
- The E refers to an exception being raised when a QNaN is encountered.
- Added unit tests for VCMP{E}

08f638d447 emit_x64: pmaxuw and pminuw require SSE 4.1
This commit is intended to close citra-emu/citra#3137.

pmaxuw and pminuw were used to perform unsigned comparisons; we emulate
these using a signed comparison by offsetting the inputs by 0x8000 for
CPUs that do not support SSE 4.1.

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.

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.
