A commit A can reach a commit B only if the generation number of A is
strictly larger than the generation number of B. This condition allows
significantly short-circuiting commit-graph walks.
On a copy of the Linux repository where HEAD is contained in v6.3-rc4
but no earlier tag, the command 'git tag --contains HEAD' of
ListTagCommand#call() had the following peformance improvement:
(excluded the startup time of the repo)
Before: 2649ms (core.commitgraph=true)
11909ms (core.commitgraph=false)
After: 91ms (core.commitgraph=true)
11934ms (core.commitgraph=false)
Bug: 574368
