Message:

Make the profiler use higher than millisecond resolution time-stamps.

Reviewed by Kevin McCullough.

• kjs/DateMath.cpp:

(KJS::getCurrentUTCTime): Call getCurrentUTCTimeWithMicroseconds and
floor the result.
(KJS::getCurrentUTCTimeWithMicroseconds): Copied from the previous
implementation of getCurrentUTCTime without the floor call.

• kjs/DateMath.h: Addded getCurrentUTCTimeWithMicroseconds.
• profiler/ProfileNode.cpp:

(KJS::ProfileNode::ProfileNode): Use getCurrentUTCTimeWithMicroseconds.
