SI-7126 Account for the alias types that don't dealias.
After this change:
qbin/scalac -Ydebug test/files/pos/t7126.scala 2>&1 | grep warning
warning: dropExistential did not progress dealiasing Test.this.T[Test.this.T], see SI-7126
one warning found

the ticket illuminate the general areas of concern.
