[Reassociate][test] Delete improper -NOT patterns to work with -enable-new-pm=1

The two tests rely on LegacyInlinerBase::doFinalization to remove
Function::isDefTriviallyDead() functions. The new PM does not have the behavior.
The -NEXT patterns checking the emptiness are actually sufficient.

Note, reassociate-deadinst.ll has become stale - it no longer catches
the problem r285380 intended. Unfortunately it is difficult to craft a
new test because it is actually pretty difficult to break it with
`MadeChange = true;` all over the file.
