A set of small bugs in sort stability for `lists:sort/1` and
`lists:keysort/1` has been fixed. The bug happened for only some, seemingly
random, element sequences. Most sorts were stable.

Sort stability for `lists:sort/1` is only possible to observe when sorting
lists with floating point and integer numbers of the same value.

For `lists:keysort/1` the list had to start with two tuples where the keys
or the whole tuples compared equal.
