Remove the opt.lg_prof_bt_max option. Remove opt.lg_prof_bt_max, and hard code it to 7. The original intention of this option was to enable faster backtracing by limiting backtrace depth. However, this makes graphical pprof output very difficult to interpret. In practice, decreasing sampling frequency is a better mechanism for limiting profiling overhead.
