Functions with v128 in their signatures are always lowered to 4 word32. So if a return happens to be have an input that is a f32x4 operation, we get a register allocator error because it tries to fit a float into a general register. To fix that we need to do some checks when lowering kReturn, and for each input node, if we are returning a v128, and it is to be lowered into 4 f32 nodes, we bitcast the floats to ints.
