perf: allow profiling of more than one run

By default, we still profile the first run only. However profiling more run help
to understand side effect from one run to the other. So we add an option to be
able to do so.

Test applying context diffs

  $ cat > writepatterns.py <<EOF
  > import sys
  > 
  > path = sys.argv[1]
  > lasteol = sys.argv[2] == '1'
  > patterns = sys.argv[3:]
  > 
  > fp = open(path, 'wb')
  > for i, pattern in enumerate(patterns):
  >     count = int(pattern[0:-1])
  >     char = pattern[-1].encode('utf8') + b'\n'
  >     if not lasteol and i == len(patterns) - 1:
  >         fp.write((char * count)[:-1])
  >     else:
  >         fp.write(char * count)
  > fp.close()
  > EOF
  $ cat > cat.py <<EOF
  > import sys
  > from mercurial.utils import procutil, stringutil
  > procutil.stdout.write(b'%s\n'
  >                       % stringutil.pprint(open(sys.argv[1], 'rb').read()))
  > EOF
