Remove Hack in compiler/nativeGen/X86/CodeGen.hs
Remove the hack around Line 3914 labeled with:
-- HACK: On x86_64 binutils<2.17 is only able to generate PC32 -- relocations, hence we only get 32-bit offsets in the jump -- table. As these offsets are always negative we need to properly -- sign extend them to 64-bit. This hack should be removed in -- conjunction with the hack in PprMach.hs/pprDataItem once -- binutils 2.17 is standard.
This bug is intended for house keeping.
