Fix interaction of operators starting with `#` and `UnboxedSums` #1063

Closed amesgen closed 10 months ago

Closes #1062

From https://downloads.haskell.org/ghc/9.6.2/docs/users_guide/exts/primitives.html:

Note that when unboxed tuples are enabled, (# is a single lexeme, so for example when using operators like # and #- you need to write ( # ) and ( #- ) rather than (#) and (#-).

It turns that this is already the case for UnboxedSums (which is implied by UnboxedTuples).
