Optimized vec::IntoIter::next_chunk impl
``` test vec::bench_next_chunk ... bench: 696 ns/iter (+/- 22) x86_64v1, pr test vec::bench_next_chunk ... bench: 309 ns/iter (+/- 4) znver2, default test vec::bench_next_chunk ... bench: 17,272 ns/iter (+/- 117) znver2, pr test vec::bench_next_chunk ... bench: 211 ns/iter (+/- 3) ``` The znver2 default impl seems to be slow due to inlining decisions. It goes through `core::array::iter_next_chunk` which has a deeper call tree.
