[profiler] This adds function butterflies to the function list.

The function list is now filtered by category by default, and sorting improved to break ties better.

Since the butterfly trees get massive, I had to start expanding the call trees on demand. This is implemented by keeping track of all ticks that cross given tree node (+ position where they crosses it). This seems to work quite well - in subsequent CL, I am planning to flip the bottom-up and top-down trees to use this.
