Backport of #85355 to release/8.0-preview4

/cc @agocke @sbomer

Customer Impact

This avoids potential perf regressions on linux compared to preview 3 in some scenarios, which shipped with PGO enabled. Perf is expected to improve for the scenarios we optimize for in dotnet-optimization.

Testing

CI testing found no functional issues with the change.

Risk

We haven't seen this change propagate to our perf benchmarks, so we don't know exactly the perf impact. Fortunately, any risk is expected to be perf-related, not correctness-related. Perf is expected to improve for scenarios that we benchmark.

IMPORTANT: If this backport is for a servicing release, please verify that:

  • If the change touches code that ships in a NuGet package, you have added the necessary package authoring and gotten it explicitly reviewed.
