ca94c75c52 Auto merge of #44220 - kennytm:fix-44216-instance-plus-max-duration-should-panic, r=alexcrichton 
Properly detect overflow in Instance ± Duration.

Fix #44216.
Fix #42622

The computation `Instant::now() + Duration::from_secs(u64::max_value())` now panics. The call `receiver.recv_timeout(Duration::from_secs(u64::max_value()))`, which involves such time addition, will also panic.

The reason #44216 arises is because of an unchecked cast from `u64` to `i64`, making the duration equivalent to -1 second.

Note that the current implementation is over-conservative, since e.g. (-2⁶²) + (2⁶³) is perfectly fine for an `i64`, yet this is rejected because (2⁶³) overflows the `i64`.

ddd123ed9a Auto merge of #44251 - kennytm:osx-backtrace, r=alexcrichton 
Add libbacktrace support for Apple platforms (resubmitted)

Resubmitting #43422 rebased on the current master (cc @JohnColanduoni).

I have added an additional commit to fallback to `dladdr`-based `resolve_symbol` if `libbacktrace` returns `None`, otherwise the stack trace will be full of `<unknown>` when you forget to pass the `-g` flag (actually it seems — at least on macOS — the `dladdr` symbol is more accurate than the `libbacktrace` one).

Properly detect overflow in Instance +/- Duration. 
Avoid unchecked cast from `u64` to `i64`. Use `try_into()` for checked
cast. (On Unix, cast to `time_t` instead of `i64`.)

d7d75eff30 Auto merge of #43931 - eddyb:const-local-key, r=alexcrichton 
Make the LocalKey facade of thread_local! inlineable cross-crate.

Fixes (almost*) #25088 by changing the `LocalKey` `static` `thread_local!` generates to a `const`.
This can be done because a `LocalKey` value holds no actual TLS data, only function pointers to get at said data, and it could even be made `Copy` without any negative consequences.
The recent stabilization of rvalue promotion to `'static` allows doing this without changing the API.
r? @alexcrichton

*almost because we can't yet inline `__getit` because it breaks on MSVC, see https://github.com/rust-lang/rust/pull/43931#issuecomment-323534214
