Remove ty_bot from the type system
...
We now instead use a fresh variable for expressions that diverge.

...
Avoid O(n^2) performance by reconsidering the full set of obligations only when we are about to report an error (#18208 ). I found it is still important to consider the full set in order to make tests like `let x: Vec<_> = obligations.iter().collect()` work.
I think we lack the infrastructure to write a regression test for this, but when I did manual testing I found a massive reduction in type-checking time for extreme examples like those found in #18208 vs stage0.

This adds impls of Eq/Ord/PartialEq/PartialOrd/Show/Default to Arc<T>, and it
also removes the `Send + Sync` bound on the `Clone` impl of Arc to make it more
deriving-friendly. The `Send + Sync` requirement is still enforce on
construction, of course!

auto merge of #18144 : bkoropoff/rust/mighty-monomorphizin-unboxed-closures, r=nikomatsakis
...
This allows unboxed closures that reference free type/region parameters to be monomorphized correctly in trans.
It was necessary to make `ty_unboxed_closure` carry around a `Substs` to accomplish this. Plumbing this through typeck revealed several areas where type/region parameters in unboxed closure types are possibly not being handled correctly. Since my goal was just to fix trans, I decided to leave FIXME comments on areas that still need attention and seek feedback on the best way to clean them up, possibly as a follow-up PR.
Closes #16791

Fix monomorphization of unboxed closures
...
This adds a `Substs` field to `ty_unboxed_closure` and plumbs basic
handling of it throughout the compiler. trans now correctly
monomorphizes captured free variables and llvm function defs. This
fixes uses of unboxed closures which reference a free type or region
parameter from their environment in either their signature or free
variables. Closes #16791
