It's getting to the point where we need to collapse away the repetition
in the four models of ArrayType. Step 1 is just integrating the
"gybbing" steps into the testing framework.

Instead of flailing about trying to find the right combination of tricks
in the standard library code itself, create a separate test file. This
demonstrates that we have everything we need to implement algorithm
specialization similar to what the C++ standard library does!
Next: moving on to apply the technique...

These protocols fix a number of problems with the existing system,
among them esoteric naming ("Indexable", "Generator"), the subtlety of
a MultiPassGenerator protocol that refines Generator without adding
any structural requirements, and questions about whether types with
reference semantics even fit into the framework. Lacks any real
testing; this merely proves that we can compile the protocols and use
them in trivial algorithms.

This code never belonged in docs/ in the first place. The other
problem was that they'd drift out-of-date, and regressions that were
only going to be caught by this code could slip into the compiler,
e.g. rdar://problem/15525229
