Implement BlockArguments (#10843)
This patch implements the BlockArguments extension, as proposed at
https://github.com/ghc-proposals/ghc-proposals/pull/90. It also
fixes #10855 as a side-effect.
This patch adds a large number of shift-reduce conflicts to the parser.
All of them concern the ambiguity as to where constructs like `if` and
`let` end. Fortunately they are resolved correctly by preferring shift.
The patch is based on @gibiansky's ArgumentDo implementation (D1219).
