This requires adding a new method, `P::filter_map`. This commit reduces instruction counts for various benchmarks by up to 0.7%.
`TryFrom<&[T]> for &[T; $N]` (note *reference* to an array) already exists, but not needing to dereference makes type inference easier for example when using `u32::from_be_bytes`. Also add doc examples doing just that.
This commit converts some 2-space indents to 4-space indents.
They are unused. The commit also adds some blank lines between some methods.
`Printer::word` takes a `&str` and converts it into a `String`, which causes an allocation. But that allocation is rarely necessary, because `&str` is almost always a `&'static str` or a `String` that won't be used again. This commit changes `Token::String` so it holds a `Cow<'static, str>` instead of a `String`, which avoids a lot of allocations.
`pretty_print` takes a `Token` and `match`es on it. But the particular `Token` kind is known at each call site, so this commit splits it into five functions: `pretty_print_eof`, `pretty_print_begin`, etc. This commit also does likewise with `print`, though there is one callsite for `print` where the `Token` kind isn't known, so a generic `print` has to stay (but it now just calls out to the various `print_*` functions).
`mir_stats` has not been used since 2b32cb9.
This commit modifies linker flavor inference to only remove the extension to the linker when performing inference if that extension is a 'exe'.
`make_solution` does not return any guidance for now
It stop asserts and panics from libstd to automatically include string output and formatting code. Use case: developing static executables smaller than 50 kilobytes, where usual formatting code is excessive while keeping debuggability in debug mode. May resolve rust-lang#54981.
I noticed on a [recent build][1] that the linkchecker stage of CI took a whopping 15 minutes of CI time for something that should be near instantaneous. Some local profiling showed some very hot functions and clones which were pretty easy to remove, and now instead of running in minutes locally it runs in seconds.

Don't panic in determining the privacy of a type if a lifetime outlives generic exists in an existential type.

Use raw_entry for more efficient interning Fixes rust-lang#56308 (comment)
Fix const_fn ICE with non-const function pointer Fixes rust-lang#56164
Implement chalk unification routines `ResolventOps` and `AggregateOps` are mostly straightforwardly translated from chalk. I had caught a few bugs already in my `chalk` branch and backported fixes to this branch, but there may be other ones left. EDIT: I hope there are none left now :) Fixes rust-lang#54935.
