[issue32534] Speed-up list.insert: use memmove()

This issue is a micro-optimization which is only 1.08x faster:

Moreover, it seems really hard to measure precisely the benefit on benchmarks. Results seem to not be reliable.

I suggest to close the issue as WONTFIX, as I cannot see any reliable speedup nor any significant impact on performance.
