The sha-1 and md-5 packages contain crates named sha1 and md5, respectively. This discrepancy makes it somewhat more challenging to automate detection of unused crates. Explicitly rename the packages to the names of the crates they contain, to simplify such detection.
This PR adds ability for the target specifications to specify frame pointer emission type that's not just “always” or “whatever cg decides”. In particular there's a new mode that allows omission of the frame pointer for leaf functions (those that don't call any other functions). We then set this new mode for Aarch64-based Apple targets. Fixes rust-lang#86196

Add suggestions for "undefined reference" link errors
This adds a suggestion for "undefined reference to ..." linking errors to install or specify the location to an external library. Since there is no defined error format for linkers, we just check if there was a failure and if that failure contains the string `undefined reference to`. This also makes it impossible to test this, since the output depends on the system linker. The output now looks like:
```
error: linking with `cc` failed: exit status: 1

Fix misleading "impl Trait" error The kinds can't be compared directly, as types with references are treated as different because the lifetimes aren't bound in ty, but are in expected. Closes rust-lang#84160
