RequirementMachine: Don't assert if a rewrite system has unresolved rules
...
This is a source-level error, not an invariant violation. Instead, plumb
a new hadError() flag, which in the future will assert if no diagnostic
was produced.

RequirementMachine: Avoid term->type->term round-trip in getConformanceAccessPath()
...
We would skip recording a conformance access path if the subject
type canonicalized to a concrete type, but this was incorrect.
The correct formulation is to use the _canonical anchor_ and not
the canonical type as the caching key; that is, we always want it
to be a type parameter, even if it is fixed to a concrete type,
because type parameters fixed to concrete types can appear in
the middle of conformance access paths, as the example in the
radar demonstrates.

RequirementMachine: Preserve sugared generic params in getSuperclassBound() and getConcreteType()
...
This was manifesting as module interfaces printing generic parameters
as `τ_0_0` in some cases.
Note that the GSB has the same bug, so this test case will fail with
-requirement-machine=off. I don't plan on fixing the bug in the GSB
unless we need to.
