Richard Smith 782bd87316 AST cloning mechanism (#2699) 
This is intended to be used for template instantiation, but for now takes no stance as to what it's cloning.

This is tested by parsing and cloning all of our test files, and checking that the result of converting each AST to proto is the same as the result of cloning and then converting each AST to proto.

Richard Smith 9007b3952d Initial support for where expressions. (#1310) 
Build constraint types from `where` expressions. This is very bare-bones; there's no support for constraining `.Self` or associated types yet, but degenerate cases not involving self-reference work.

`==` constraints are syntactically supported but not semantically verified yet, and they aren't used for anything.
