Removes howMany values at the front or back of the
container. Unlike the unparameterized versions above, these functions
do not throw if they could not remove howMany elements. Instead,
if howMany > n, all elements are removed. The returned value is
the effective number of elements removed. The stable version behaves
the same, but guarantees that ranges iterating over the container are
never invalidated.
