Introduce adjustFixupOffset that adjusts the fixup offset of a relocation.

Browse Source 
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.
