[llvm] [NewPM] Fix OptBisect Functionality for disabled gate (PR #225437)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/225437

We were never actually checking if the gate was enabled. This patch
fixes it to match the behavior of the LegacyPM.
