Auto merge of #52166 - orlp:master, r=joshtriplett
Performance improvement of Vec's swap_remove. The old implementation *literally* swapped and then removed, which resulted in unnecessary move instructions. The new implementation does use unsafe code, but is easy to see that it is correct. Fixes https://github.com/rust-lang/rust/issues/52150.
