High memory use when compiling many let bindings.

Two programs that generate modules with lots of let bindings that GHC struggles to compile. With the first,
ghc -c J.hs
uses >100M of memory which seems a little high. For the second,
ghc -c J2.hs
got past 700M before I killed it, with both 6.6 and HEAD.
