Jordan Rose 2d84981fc2 Improve the mangling of typealiases. ...

- Allow them to use substitutions.
- Consistently use 'a' as a mangling operator.
- For generic typealiases, include the alias as context for any generic
  parameters.

Typealiases don't show up in symbol names, which always refer to
canonical types, but they are mangled for debug info and for USRs
(unique identifiers used by SourceKit), so it's good to get this
right.
