The canonical way of creating a constant i31ref value for GC languages is the sequence of:
(i31.new (i32.const X))
Today we will load the i32 constant into a register than compute the i31ref value from it using some arithmetic. We could optimize this so that we perform the i31ref conversion at compile-time and just load the result as a constant at runtime.
