Cherry Zhang 585b52261c runtime: remove deferreturn dummy argument
deferreturn has a dummy argument, that is only used for getting
the caller's SP. When generating deferreturn calls, the compiler
does not pass an actual argument or reserve its stack space.
Also, the current code is written with the assumption about where
the argument's address is on the stack. Currently this is correct
for both ABI0 and the register ABI, but it may change in the
future (e.g. if we remove dedicated spill slots). Remove the
argument.

Also remove the argument for getargp.
