  Log:
  Turn off peephole optimizations if we're at the start of a basic block,
  where they are certainly incorrect.  The bug was reported in
  http://www.haskell.org//pipermail/hugs-bugs/2004-October/001517.html
  but is ancient.
  
  Also re-enabled the LOAD+EVAL optimization that was disabled in rev 1.8
  as a partial workaround for another instance of this bug, reported in
  http://www.haskell.org/pipermail/hugs-bugs/2002-May/000708.html
