It's strange to duplicate the logic for emitting FP values into emitGlobalConstantDataSequential, and it's even stranger that we end up printing the verbose assembly comments differently between the two paths. Just call into emitGlobalConstantFP rather than crudely duplicating its logic. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@254988 91177308-0d34-0410-b5e6-96231b3b80d8
