Fix for Attempt to fix [CGData][MachineOutliner] Global Outlining (#90074) #108037 (#108047)
The previous `attempt to fix [CGData][MachineOutliner] Global Outlining
(#90074) #108037` was incomplete because the
`ImmutableModuleSummaryIndexWrapperPass` is now optional for the
MachineOutliner pass.
With this fix, the test file `CodeGen/AArch64/O3-pipeline.ll` shows no
changes compared to its state before `[CGData][MachineOutliner] Global
Outlining (#90074)`.
