  -----------
  [MemProf] Emit remarks when hinting allocations not needing cloning (#141859)

The context disambiguation code already emits remarks when hinting
allocations (by adding hotness attributes) during cloning. However,
we did not yet emit hints when applying the hotness attributes during
building of the metadata (during matching and again after inlining).
Add remarks when we apply the hint attributes for these
non-context-sensitive allocations.
