When using `..` somewhere other than the end, parse the rest of the
pattern correctly while still emitting an error.
Add suggestions to either remove trailing `,` or moving the `..` to the
end.
We currently give a specific message when encountering a `..` anywhere
other than the end of a pattern. Modify the parser to accept it (while
still emitting the error) so that we don't also trigger "missing fields
in pattern" errors afterwards.
Optimize layout calculations in HashMap
This now produces the same assembly code as the previous implementation.

Do not promote union field accesses
r? @eddyb
technically a breaking change, but the code errored on the previous stable and produces UB + a warning on the current stable. I don't think we need a crater run in that case.
Remove the unused `-Z trans-time-graph` flag.
Rebase of #50783 has accidentally revived the flag (which should be renamed to `-Z codegen-time-graph` by #50615).
Generate br for all two target SwitchInts
Instead of only for booleans. This means that `if let` also becomes a br.
Apart from making the IR slightly simpler, this is supported by FastISel (#4353).
const fn integer operations
A follow up to #51171Fixes#51267
Makes a lot of the integer methods (`swap_bytes`, `count_ones` etc) `const fn`s. See #51267 for a discussion about why this is wanted and the solution used.
Remove rustdoc-specific is_import field from HIR
Fixes#47100.
I believe that there is no need to check for the name being the same, as this
part of rustdoc seems to be strictly interested in exploring "public modules."
Re-exports from the same module cannot visit another module; and, re-exports
cannot export items with a greater visibility than that item declares.
Therefore, I think this code is either sufficient, or in fact does more than
is necessary, depending on whether rustdoc cares about the re-export itself.
