The Patch 1 is a follow-up patch for Ian's ("Fix topdown event weak
grouping")[1].

The patch 2 is to fix the perf metrics topdown events in a mixed group.
It reuses the function introduced in [1].
Patch 1 & 2 should be on top of [1].

The patch 3 & 4 are to fix other perf metrics topdown related issues.
They can be merged separately.
