name-rev: put struct rev_name into commit slab ...
The commit slab commit_rev_name contains a pointer to a struct rev_name,
and the actual struct is allocated separatly. Avoid that allocation and
pointer indirection by storing the full struct in the commit slab. Use
the tip_name member pointer to determine if the returned struct is
initialized.
Performance in the Linux repository measured with hyperfine before:
Benchmark #1 : ./git -C ../linux/ name-rev --all
Time (mean ± σ): 953.5 ms ± 6.3 ms [User: 901.2 ms, System: 52.1 ms]
Range (min … max): 945.2 ms … 968.5 ms 10 runs
... and with this patch:
Benchmark #1 : ./git -C ../linux/ name-rev --all
Time (mean ± σ): 851.0 ms ± 3.1 ms [User: 807.4 ms, System: 43.6 ms]
