[issue14309] Deprecate time.clock()

time.clock() is not portable: it is a different clock depending on the OS. To write portable code, you have to use the right function:

 - time.time()
 - time.steady()
 - os.times(), resource.getrusage()

On Windows, time.clock() should be replaced by time.steady(). On UNIX, time.clock() can be replaced with "usage=os.times(); usage[0]+usage[1]" for example.

Which kind of use case is not covered by these functions?
