Image base is the PE/COFF base address (the relocated one) - pointer to
In ELF the PIC calculations use PC + offset to GOT, so the image base would
be actually PC minus assumed PC offset, or GOT minus assumed GOT offset
(offset taken from the ELF header)

I guess that could be easy calculated using MachineInstruction. Just
thinking if something can be done using IR and GlobalVariables..
