Signed and unsigned don't quite capture the essence of what the different
combinations of x86 flags are doing for SubX. The crucial distinction is
that one set of comparison operators is for integers and the second is
for addresses.

When I created it I was conflating two things:
a) needing to refer to just the start, rather than the whole, and
b) counting indirections.
Both are kinda ill-posed. Now Mu will have just `addr` and `handle` types.
Normal types will translate implicitly to `addr` types, while `handle`
will always require explicit handling.

Try to make the comments consistent with the type system we'll eventually
have.

Standardize conventions for labels within objects in the data segment.
We're going to use this in a new tool.

Clean up pseudocode to match planned syntax for the type- and memory-safe
level-2 Mu language.
http://akkartik.name/post/mu-2019-2 is already out of date.

Move stack operations to a layer of their own.
It was some short-term pain to take out the syntax sugar from it, but we
need access to this layer from braces, which can't depend on sugar since
it's part of sugar. Just simpler to keep one clear line and not have to
build sometimes with some sugar but not others.

This undoes 5672 in favor of a new plan:
Layers 000 - 099 are for running without syntax sugar. We use them for
building syntax-sugar passes.
Layers 100 and up are for running with all syntax sugar.
The layers are arranged in approximate order so more phases rely on earlier
layers than later ones.
I plan to not use intermediate syntax sugar (just sigils without calls,
or sigils and calls without braces) anywhere except in the specific passes
implementing them.
