14bfd557f3 Checkin testcase that was just sitting in my tree. Looks like backreferences 
have some problem in the parser, oh joy.

f6c6be2891 1. Fix bug test/Regression/Other/2002-03-20-LevelRaiseBadCodegen.ll 
2. Allow negative scales in ConvertableToGEP, so that this loop from
   alloc_tree in the Olden health benchmark is correctly raised:

       for (i = 3; i >= 0; i--)
         fval[i] = alloc_tree(level - 1, label*4 + i + 1, new);

   Stepping through the array backwards caused a negative scale.
