Remove StgLam
StgLam is used exclusively in the work of CoreToStg, but there's nothing
in the type of StgExpr that indicates this, so we're forced throughout
the Stg.* codebase to handle cases like:
case expr of
...
StgLam lam -> panic "Unexpected StgLam"
...
This patch removes the StgLam constructor from the base StgExpr so these
cases no longer need to be handled. Instead, we use a new intermediate
type in CoreToStg, PreStgRhs, to represent the RHS expression of a
binding.
