Sorting of DeclContext-local protocols and conformances shouldn't ever
be necessary, because the underlying data structures that produce
these lists should be deterministic. Sorting can hide any
non-determinism, so stop doing it and we can address the underlying
nondeterminism.
Several tests only work when standard library declarations are listed in a certain order. This change weakens those tests enough to tolerate ordering changes.

We want to make sure that if someone replaces the synthesized
implementation with a handwritten one, it doesn't change the ABI.
The simplest way to do that is to not use this clever workaround.

Protocol name mangling didn’t always go through a path that allowed the use
of standard substitutions. Enable standard substitutions for protocol name
manglings where they make sense.
Removes ~277k from the standard library binary size.
