Specialize Enumerable#max and Enumerable#min for Range

This patch prevents a hang for pathalogical (large) Ranges when
computing max and min.

Range inherits its implementation of max and min from Enumerable.
Enumerable implements max and min by calling each. For Range objects,
this is unnecessary since we know the max and the min by the end and
begin attributes.

It is also very slow. This code hangs unnecessarily:

    (0..2**32).max
    # ... hang
    (0..2**32).min
    # ... hang

This patch overrides max and min after including enumerable to yield
based on the begin and end methods.
