bmeurer a210c3757e [runtime] Remove the very dangerous %_CallFunction intrinsic.
The %_CallFunction doesn't implement the call sequence properly, it
doesn't do the receiver wrapping, nor does it check for
classConstructor. Also the eager deoptimization for %_CallFunction was
seriously b0rked (we must have been lucky with TurboFan so far).
