[issue4207] Remove backwards compatibility in _heapq for performance

[Raymond Hettinger]

Raymond Hettinger <rhettinger at users.sourceforge.net> added the comment:

The compatability code was just added in Py2.6 and is needed for apps
like Twisted that currently rely on __le__ being tested.  In 3.0, the
compatability code is removed and full speed is restored.

Also, the timing suite exaggerates the effect.  A more typical use of
heaps involves a heap of tuples with the first tuple element being used
as a priority level.  That increases the comparison time and decreases
the relative significance of the dispatch logic.
