…in_overflow, r=m-ou-se Avoid overflow in `VecDeque::with_capacity_in()`. The overflow only happens if alloc is compiled with overflow checks enabled and the passed capacity is greater or equal 2^(usize::BITS-1). The overflow shadows the expected "capacity overflow" panic leading to a test failure if overflow checks are enabled for std in the CI. Unblocks [CI: Enable overflow checks for test (non-dist) builds rust-lang#89776](rust-lang#89776). For some reason the overflow is only observable with optimization turned off, but that is a separate issue.
