We used to update profiler ticks after tiering up decisions when tiering
up from Ignition and update the ticks before when tiering up from
mid-tier optimized code. This meant we added special cases to account for
this difference. This cl makes updating the ticks uniform by always
updating the ticks before tiering up decisions. Also adjusts the
heuristics to take this into account.
