  [libc++] Use a median-of-3 for the A/B comparison benchmarking job (#208023)

After a bit of testing, I think this provides a good tradeoff between
resource utilization and noise reduction. Furthermore, the comparison
script (which produces the output) will be augmented to surface the
variability of the results in a separate PR.

  [flang][OpenMP][NFC] Share SetSymbolDSA between semantics and lowering (#207826)

Move the DSA helper from the private OmpAttributeVisitor::SetSymbolDSA
into the public openmp-dsa header next to GetSymbolDSA, and share the
DSA flag set through a single GetDataSharingAttributeFlags().

This lets an upcoming metadirective lowering change reuse the helper to
set the predetermined DSA of the loop induction variables of a selected
variant. A loop-associated variant is resolved during lowering, so the
usual semantic DSA resolution never runs on its loop nest and lowering
must set those flags itself.

Assisted with Copilot.
