Pushed now. I've done some benchmarks on shell, on tip-of-tree GMP (no
local changes). See numbers at the end of this message, comparing
mpn_mul_basecase, mpn_toom22_mul and mpn_toom32_mul.
Every single tuneup invocation made by the nightly builds in the last
few weeks have failed. The last time it worked was around 2023-09-27.
The changes made around that time ought to be the culprit.
Failures with tuneup cause the autobuild system to rerun things 5 times;
that's my electricity bill...
Please test any changes before checking them in. And please also follow up
test results at e.g., https://gmplib.org/devel/tm/gmp/date!
