In the case of soft-fp (e.g. fp128 under wasm) the result of getTypeLegalizationCost() can be an integer type even if the input is floating point (See LegalizeTypeAction::TypeSoftenFloat). Before calling isFabsFree() (which asserts if given a non-fp type) we need to check that that result is fp. This is safe since in fabs is certainly not free in the soft-fp case.
