name-rev: generate name strings only if they are better
Leave setting the tip_name member of struct rev_name to callers of
create_or_update_name(). This avoids allocations for names that are
rejected by that function. Here's how this affects the runtime when
working with a fresh clone of Git's own repository; performance numbers
by hyperfine before:
Benchmark #1: ./git -C ../git-pristine/ name-rev --all
Time (mean ± σ): 437.8 ms ± 4.0 ms [User: 422.5 ms, System: 15.2 ms]
Range (min … max): 432.8 ms … 446.3 ms 10 runs
... and with this patch:
Benchmark #1: ./git -C ../git-pristine/ name-rev --all
Time (mean ± σ): 408.5 ms ± 1.4 ms [User: 387.2 ms, System: 21.2 ms]
Range (min … max): 407.1 ms … 411.7 ms 10 runs
