In preparation for C# 9.0, I added support for more pattern matching.
Because of the extremely context-sensitive nature of the new pattern matching, a lot of the new features are crudely approximated. It's not ideal but the pattern matching grammar is so complex that I can't think of anything better.
Because
switchstatements and expression got a whole lot more complex, I also added a few new tests.I make separate PRs for other new syntactic features of C# 9.0 after they get finalized.
