  1. Remove solve_nll_region_constraints measurements from `-Ztime-passe… 

    …s` output.

Because it pollutes the output with hundreds or thousands of
uninteresting lines for which the time duration is always(?) 0.000s.

  2. Add a "total" measurement to -Ztime-passes. 

    This is useful for getting the total compilation time at the end.
To do this, the patch changes `print_time_passes_entry` to not increment
the depth, which means that `print_time_passes_entry_internal` is no
longer needed.
