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
{{{#!hs
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.
