Parser: consolidate handleCaseMatch and endCaseExpression.
...
There was no need for both of these listener callbacks, because they
were always called together. Since `beginCaseExpression` is actually
used, it makes sense to keep `endCaseExpression` and get rid of
`handleCaseMatch`.

Parser and listener API changes for supporting pattern guards.
...
These are in their own CL so that it's easy to verify that no
functionalty has changed, even though a lot of parser expectations
files are affected.
In a follow-up CL, I'll add code that actually parses pattern guards.

Parser: add support for wildcard patterns.
...
The bare identifier `_` is treated as a variable pattern wherever it
appears, even though other bare identifiers are sometimes treated as
constant patterns.
