[Bye] Remove legacy pipeline registration

D137915 has somehow caused a flang bot to fail: https://lab.llvm.org/buildbot/#/builders/191/builds/11279.

Given that the issue is with the legacy pipeline registration code and the legacy pipeline registration infrastructure is to be removed soon, remove this part of Bye.
