Use named fields for `{ast,hir}::ItemKind::Impl`

Currently, the widely used `ItemKind::Impl` variant is a tuple with seven fields. I want to add an eighth in rust-lang#68140, which means I have to update most matches on this variant anyways. Giving a name to each field improves readability and makes future changes of this nature much simpler.

This change will cause several tools to break. I will fix them once this is merged.

Do not ICE on malformed suggestion spans

Under the assumption that suggestions are by their very nature always "best effort", it is ok if we don't display them instead of having an ICE. The underlying issue of the malformed span being _created_ is left unaddressed.

Fix rust-lang#67567.

Add regression test for integer literals in generic arguments in where clauses

Closes rust-lang#67753.

Stop treating `FalseEdges` and `FalseUnwind` as having semantic value for const eval

This change does not expose loops or conditions to stable const fns because we check those at the HIR level and in the regular const validity checks.
