1120c8b34a Many changes 
* Simplify a lot of the inlining stuff.  There are still problems, but not
  many
* Break up the Function representation to have a vector for every different
  node type so it is fast to find nodes of a particular flavor.
* Do more intelligent merging of call values
* Allow elimination of unreachable shadow and allocation nodes
* Generalize indistinguishability testing to allow merging of identical calls.
* Increase shadow node merging power

  implemented.

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

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.
