Merge #2252

2252: Fix parsing of "postfix" range expressions. r=matklad a=goffrie

Right now they are handled in `postfix_dot_expr`, but that doesn't allow it to
correctly handle precedence. Integrate it more tightly with the Pratt parser
instead.

Also includes a drive-by fix for parsing `match .. {}`.

Fixes #2242.
