[turbofan] Remove the function reload hack for OSR.

Initially we were unable to address certain stack slots in the callee
part of the frame, including the function marker, therefore we had to
hack a reload of the function register into the OSR prologue. Now that
we are able to address all stack slots, we no longer need this hack.
