9e77f7e08b Make ConvertableToGEP handle cases where the user is indexing into the
first element of a structure type.  Before this would not be handled because
getStructOffset would either stop immediately (because StopEarly was true
and Offset = 0), or blast past the level we wanted.

Now ConvertableToGEP steps down through the type one level at a time, checking
the Offset and Scale conditions at each step

45ef5c26d4 Fix the: test/Regression/Other/2002-03-20-LevelRaiseCrash.ll bug. It turned
out that almost always the result of the add was the same as the GEP that
would be generated.  In this case, however, it wasn't, so bad things happened.

99fb91cc2f 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.
