[PowerPC] Remove need for adjustFixupOffst hack

Now that applyFixup understands differently-sized fixups, we can define
fixup_ppc_lo16/fixup_ppc_lo16_ds/fixup_ppc_ha16 to properly be 2-byte
fixups, applied at an offset of 2 relative to the start of the 
instruction text.

This has the benefit that if we actually need to generate a real
relocation record, its address will come out correctly automatically,
without having to fiddle with the offset in adjustFixupOffset.

Tested on both 64-bit and 32-bit PowerPC, using external and
integrated assembler.
