This re-exports the primitive types from libcore at `core::primitive` to allow
macro authors to have a reliable location to use them from.
Take advantage of the fact that `check_mod_attrs` marks attributes as
used and change their type to normal, so that any remaining uses will be
warned about by the unused attribute lint.

Add primitive module to libcore

This re-exports the primitive types from libcore at `core::primitive` to allow
macro authors to have a reliable location to use them from.

Fixes rust-lang#44865

Deduplicate identifier printing a bit

rust-lang#67010 introduced a couple more subtly different ways to print an identifier.
This PR attempts to restore the order.

The most basic identifier printing interface is `Formatter`-based now, so `String`s are not allocated unless required.

Mark attributes consumed by `check_mod_attrs` as normal

Take advantage of the fact that `check_mod_attrs` marks attributes as
used and change their type to normal, so that any remaining uses will be
warned about by the unused attribute lint.

This rollup caused a large regression for incremental builds of serde and encoding. The self-profile results indicate that crate_lints time has increased greatly.

Could either of those be the cause? Whichever PR is the cause should be backed out.

@nnethercote Changes from #69412 are most likely the cause. They introduced a functional regression, which has significant performance impact as well. Revert is in #69513. Thanks for catching this.
