Also, add a flag to marked nodes that do not need code because they
have been folded into the user (parent in the BURG tree).

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

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.
