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

out that almost always the result of the add was the same as the GEP that

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.
