RSG (Ryan Specialty Group) recently announced a rename to Ryan Specialty (no
"Group"), but I'm not sure if the legal name has been changed yet or not, so
I'll wait on that.
See the previous commit. There is no sense in some common "IR" namespace,
since those IRs should live close to whatever system whose data they
represent.
In the case of these, they are general IRs that can apply to many different
parts of the system. If that proves to be a false statement, they'll be
moved.

The IRs really ought to live where they are owned, especially given that
"IR" is so generic that it makes no sense for there to be a single location
for them; they're just data structures coupled with different phases of
compilation.
This will be renamed next commit; see that for details.
This also removes some documentation describing the lowering process,
because it's undergone a number of changes and needs to be accurately
re-summarized in another location. That will come at a later time after the
work is further along so that I don't have to keep spending the time
rewriting it.
DEV-10863
This has been a long time coming, and has been repeatedly stashed as other
parts of the system have evolved to support it. The introduction of the XIR
tree was to write tests for this (which are sloppy atm).
This currently writes out the `xmle` header and _most_ of the `l:dep`
section; it's missing the object-type-specific attributes. There is,
relatively speaking, not much more work to do here.
The feature flag `wip-xir-xmle-writer` was introduced to toggle this system
in place of `XmleWriter`. Initial benchmarks show that it will be
competitive with the quick-xml-based writer, but remember that is not the
goal: the purpose of this is to test XIR in a production system before we
continue to implement it for a frontend, and to refactor so that we do not
have multiple implementations writing XML files (once we echo the source XML
files).
I'm excited to get this done with so that I can move on. This has been
rather exhausting.
This is garbage code. Do not use it. It is intentionally throwaway.
While I've researched Rust, I haven't actually _used_ it for a project, so
this is a combination of me exploring various ways of accomplishing the
problem and forcing myself to learn certain aspects of the language.
I'll likely be using petgraph, and this also currently lacks symbol
abstractions. This commit also performs far too much heap allocation
copying strings around. But it _does_ perform the topological sort.
Since this only stores the symbol name, it lacks enough information about
the symbol to perform a proper linking.
