[fpc-pascal] Sub-millisecond time measuring

[Hairy Pixels]

I had a large function which I was profiling with MilliSecondsBetween but I split it to be called many different times and now it's not accumulating the total time correctly because time is being lost to due millisecond precision.

Is there anything in the RTL I can use which is more accurate? I searched and couldn't find anything.
