Rework HsValBindsLR
Once Trees that Grow has been applied to the hsSyn AST, rework HsValBindsLR to simplify it.
From a comment on https://phabricator.haskell.org/D4147
Nothing here gives any clue that this is intended for the output of the renamer. And typechecker I think.
Plus I wonder if we'd be better served by
data HsValBindsLR idL idR
= ValBinds
[(RecFlag, LHsBindsLR idL idR)]
[LSig GhcRn]Then the parser can generate a giant singleton Rec and the renamer can sort it out. Less fuss.
