> Original change's description:
> > [heap] Invoke allocation observers before limiting the LAB
> >
> > Currently whenever we reach a step we get a small LAB the same size as
> > the allocated object. This is becuase the remaining step size is smaller
> > then the current allocation.
> > Invoking observers before limiting the LAB, and thus updating step
> > sizes, should eliminate the small LAB we get whenever we reach a step.
> >
> > Drive-by: remove redundant method arguments.
