Auto merge of #25095 - huonw:faster-bitvec, r=alexcrichton
This makes the `bit::vec::bench::bench_bit_vec_big_union` benchmark go from `774 ns/iter (+/- 190)` to `602 ns/iter (+/- 5)`. (There's room for more work here too: if one can guarantee 128-bit alignment for the vector, the compiler actually optimises `union`, `intersection` etc. to SIMD instructions, which end up being ~5x faster that the original version, and 4x faster than the optimised version in this patch.)
