Commit Message

On targets where the callee may make a copy of incoming aggregates DSE
would trigger in both functions -- prior to inlining of course.

This patch tightens the test to look for DSE triggering in the spot
where we really wanted to check for it.  It's not strictly a regression
fix, but given it's a testsuite only change it seems appropriate.

Verified it fixes the failure on the hppa targets (prior to the ABI
change) as well as that it still passes on x86_64.

Installed on the trunk,

Jeff
