The introduction relative line number support in the dg framework was
absolutely a good thing in terms of testsuite maintenance.  However, it
also made it possible to have duplicated testnames.

The duplicated names cause our summary analysis scripts major headaches
if one of the tests pass and the other fails.  This patch fixes a couple
of instances that have have caused problems in my tester. This is by no
means comprehensive, in fact, it's likely just a drop in the bucket.

Installing on the trunk,
