Subject: Introduce adjustFixupOffset that adjusts the fixup offset of a
 relocation. This is meant to be overriden by backends. Implement an override
 on PowerPC which adjusts the offset by 2 for ha16/lo16 relocation kinds. This
 removes a commented out hack and enables hello world to be compiled on
 PowerPC.
