Auto merge of #144841 - cjgillot:typeck-no-attrs, r=davidtwco

Access less HIR attributes from typeck

Typeck relies on attributes to modify its own behaviour. This is a problem, as this means that `typeck(some function)` may depend on the span and doc-comments of many other functions.

This PR attempts to reduce such accesses to attributes. This yields to a sizeable perf improvement: https://github.com/rust-lang/rust/pull/144841#issuecomment-3153339771

Fixes https://github.com/rust-lang/rust/issues/124352
