Rollup merge of #57589 - scottmcm:vec-set_len-debug_assert, r=alexcrichton
Add a debug_assert to Vec::set_len Following the precedent of https://github.com/rust-lang/rust/pull/52972, which found https://github.com/llogiq/bytecount/pull/42. (This may well make a test fail; let's see what Travis says.)
