RequirementMachine: Generalize hack that allows associated type inheritance clauses to reference protocol typealiases
...
We want to allow this for all conformance requirements written in protocols
or the `where` clause of protocol extensions.

RequirementMachine: Introduce 'concrete contraction' pre-processing pass before building rewrite system
...
See the comment at the top of ConcreteContraction.cpp for a detailed explanation.
This can be turned off with the -disable-requirement-machine-concrete-contraction
pass, mostly meant for testing. A few tests now run with this pass both enabled
and disabled, to exercise code paths which are otherwise trivially avoided by
concrete contraction.

RequirementMachine: Introduce rules for protocol typealiases from requirement signatures
...
When building a rewrite system for a generic signature or protocol,
we would add requirements from the requirement signature of every
protocol dependency. Now, also add protocol typealias rules as well.

RequirementMachine: Track known protocols in the rewrite system
...
Conditional requirement inference needs to be able to add rewrite rules
from the requirement signatures of hitherto-unseen protocols, so to
help with that, extract out the RuleBuilder's ProtocolMap and move it
into the RewriteSystem.
