Add a cctest that contains a function with a SIMD parameter, and calls that function. This will exercise two cases in Liftoff which involves preparing to call the function, and processing the SIMD parameters of the function. The tricky case here is ARM, which requires an FP pair. Most of the logic added is to check the RegClass/type and construct the right type of LiftoffRegister to use. As a drive-by, added SIMD case to the various backends' Move implementation. This is not exercised by the test case, requires more complicated function setup.
