they modify (be conservative!)

modifies the underlying program)

Changes to:
...
* Fix bug printing method types (oops when converting previous code)
* Move some of the code from Constant::getStrValue implementations here.
This allows us to do a MUCH MUCH better job printing out complex constant
values (think an array of structure pointers), because we print symbolic
type names instead of structural. The assistance when debugging is immense
Eventually, Constant::getStrValue should be removed (it existed before because
the asmwriter file was not in VMCore), and everyone should go through the
asmwriter that want's equivalent functionality.

* The change to fix these bugs was the to ValTypeBase::refineAbstractType
method. Basically we #if 0'd out the chunk of code there and make the
table get reorganized EVEN IF the type has the same pointer. Merging
opportunities were being missed!

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.
