Michael Gottesman b50d878f5d [parse/sema] Give all case bodies their own var decls without using those var decls for anything. ...

This is a step in the direction of fixing the fallthrough bug. Specifically, in
this commit I give case stmts a set of var decls for the bodies of the case
statement. I have not wired them up to anything except the var decl
list/typechecking.
