Chris Lattner b9d9e0ff8d - Change getelementptr instruction to use long indexes instead of uint
indexes for sequential types.

Chris Lattner 28a01b2069 * Clean up the code a bit
* Allow structs with negative offsets.  This enables the em3d benchmark to
  be made typesafe.  In this case, the struct had an array as the first
  element, so a negative index was ok (the expr was -8 + 8x)

Chris Lattner 62b7fd136e Change references to the Method class to be references to the Function
class.  The Method class is obsolete (renamed) and all references to it
are being converted over to Function.

Chris Lattner 06707765fa 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

Chris Lattner f6c6be2891 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.
