Ticket #1136 (closed bug: fixed)
High memory use when compiling many let bindings.

|Type of failure:||Compile-time performance bug||Difficulty:||Unknown|
|Test Case:||Blocked By:|
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.
