  Revert "[flang] Enable alias tags pass by default (#73111)" (#73821)

This reverts commit caba0314cf631a3ba3e982cbcdc455224046c7a8.

Serious performance regressions were reported by @vzakhari
https://github.com/llvm/llvm-project/issues/58303#issuecomment-1830754173

Fixing this doesn't look quick so I will revert for now.
