    [wasm] Introduce builtin for grow_memory · edfcba04
    Clemens Hammacher authored
    This CL adds a builtin which receives an int32 argument and returns the
    int32 result. Internally, it checks whether the argument is in the
    valid smi range, then calls the runtime function with the smi argument
    and converts the return value back from smi to int32.
    This saves a lot of code in the wasm TF builder and in Liftoff.
