Auto merge of #98324 - conradludgate:write-vectored-vec, r=Mark-Simulacrum
attempt to optimise vectored write benchmarked: old: ``` test io::cursor::tests::bench_write_vec ... bench: 68 ns/iter (+/- 2) test io::cursor::tests::bench_write_vec_vectored ... bench: 913 ns/iter (+/- 31) ``` new: ``` test io::cursor::tests::bench_write_vec ... bench: 64 ns/iter (+/- 0) test io::cursor::tests::bench_write_vec_vectored ... bench: 747 ns/iter (+/- 27) ``` More unsafe than I wanted (and less gains) in the end, but it still does the job
