Fixed a previous patch.

BitKeeper/etc/ignore:
  added libmysqld/sql_profile.cc
client/mysqltest.c:
  Use my_micro_time() instead of my_getsystime() for
  faster execution.
include/config-win.h:
  Moved a definition into a header file.
mysys/my_getsystime.c:
  Use GetSystemTimeAsFileTime() instead of QueryPerformanceCounter()
  for faster execution.
