c2b5cb5619 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

14fe793707 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.

72367834b0 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.
