Patch: Backport change to g++.dg/opt/pr15551.C

[Steve Ellcey]

The test g++.dg/opt/pr15551.C was updated on the main line by Dave
Edelsohn.  The test still fails on the 4.0 and 4.1 branches because that
test change was not backported.

Is it OK if I backport his change to the 4.0 and 4.1 branches?  I
believe this qualifies as a regression because 4.0 did not have the
unlink in the source.  It was added on the branches after 4.0.0 and
4.1.0 were released and that is what is causing the problem fixed by
Dave's patch.
