QDateTime - Optimize date() and time() methods

Optimize the performance of date() and time(), resulting in a one-third
improvement, and subsequent improvements in all date/time based
functions.  Tested over 1000 iterations of the standard benchmarks, in
msecs per iteration:
                     Before  After
date()/time()        0.3     0.2
setDate()/setTime()  0.9     0.8
daysTo()             0.6     0.4

Note original performance before msecs storage was 0.06.
