[Utils] Added the ability to print the pass number and IR after it is triggered

As part of this patch, 2 options have been added:
print-pass-numbers and print-after-pass-number.

1) The print-pass-numbers option allows to print the pass names and their ordinals.
   The output of the option looks like this:
                Running pass ORDINAL PASS_NAME

2) The print-after-pass-number option allows to print IR after pass with the number
   which reported by print-passes-names.
