Hi,
Everytime the static pass number of passes change, testsuite output for dump-
noaddr will change, leading to a series of noise lines like the following
under dg-cmp-results:

This patch solve this problem by replacing the static pass number in the
output by a star, allowing for a stable output while retaining easy copy/
pasting in shell.

Is this ok for stage3?
