Revert invalid r111792. Jump tables are not broken on x86-64 / coff,
it's COFF emitter which does not support differences of two symbols (and needs to be fixed). GAS is pretty fine with code produced. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@111801 91177308-0d34-0410-b5e6-96231b3b80d8
