  Log Message:
  -----------
  Introduce new quiet mode and new option handling for -print-changed.
Summary:
Introduce a new mode of operation for -print-changed that only reports
after a pass changes the IR with all of the other messages suppressed (ie,
no initial IR and no messages about ignored, filtered or non-modifying
passes).

The option processing for -print-changed is changed to take an optional
string indicating options for print-changed. Initially, the only option
supported is quiet (as described above). This new quiet mode is specified
with -print-changed=quiet while -print-changed will continue to function
in the same way. It is intended that there will be more options in the
future.
