[cost] Mask min/max symbols when printing big O

Browse Source 
Summary: We want to keep big O notation as simple as possible in cost analysis reports (especially in diff time). Therefore, let's not show constants/min/max in big O notations even though the resulting asymptotic bound might be inaccurate. Developers can click on the trace and see the actual cost.
