FYI, PR27727 ("Remove loop...") seems to be a bit slower than the previous 
commit (f08e6d1bb3c5655f184af88c6793e90908bb6338) on my Windows build 
(msvc14.29.16.10). pyperformance shows that

  Windows x64 PGO: 34 slower, 11 faster, 13 not significant, Geometric mean: 
1.02x slower
  Windows x86 PGO: 28 slower, 17 faster, 13 not significant, Geometric mean: 
1.02x slower

Undoing PR27727 on current cpython-main branch also get speed-ups by 1-2% on 
average.
