    [wasm-simd][liftoff] Handle SIMD params in function · 8bcee191
    Ng Zhi An authored
    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.
