UseSoftFloat was removed from the TargetOptions in LLVM3.7. It's replacement (I believe) is the "+soft-float" target feature (in the target feature string). Inside LLVM, the "use-soft-float" attribute is upgraded to the "+soft-float" feature, so we can do that ourselves when creating the target machine.

(at the point where we add the attributes to the function, we have no access to whether our TargetMachine was created with FloatABI:SoftFP or not)
