  -----------
  [opt][NewPM] Add basic-aa in legacy PM compatibility mode

The legacy PM alias analysis pipeline by default includes basic-aa.
When running `opt -foo-pass` under the NPM and -disable-basic-aa is not
specified, use basic-aa.

This decreases the number of check-llvm failures under NPM from 913 to 752.
