…r=Mark-Simulacrum mark some panicking methods around Duration as track_caller Currently when they panic it looks like this ``` 0.005045 ---- instant_checked_duration_since_nopanic stdout ---- 0.000039 0.000009 thread 'instant_checked_duration_since_nopanic' (2) panicked at /home/runner/work/miri-test-libstd/miri-test-libstd/rust-src-patched/library/std/src/time.rs:445:33: 0.000007 overflow when subtracting duration from instant 0.000006 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace 0.000007 note: in Miri, you may have to set `MIRIFLAGS=-Zmiri-env-forward=RUST_BACKTRACE` for the environment variable to have an effect ``` That's pretty useless. Also fix the panic message while we are at it.
