…emove unsafe from usages"

We can't drop the `unsafe` here because it is required at the `libm`
MSRV. Instead, we will need to `allow` the lint.

This reverts commit 96ac3624abc144db930d94504a9c67aad7b949ed.

Make it easier to run the same steps outside of GitHub Actions.

  a built-in for this functionality.

Similarly to i686 and X86_64 MinGW targets, Rust needs to provide the
right chkstk symbol for AArch64 to avoid relying on the linker to
provide it.

CC rust-lang#150725

This commit moves a query to `associated_item_defs` from above an error
condition caused independently of it to below it.

It looks generally cleaner and might potentially save some runtime in
case the error condition is met, rendering `items` to be left unused,
yet still queried.

tidy: add if-installed prefix condition to extra checks system

Ref: https://rust-lang.zulipchat.com/#narrow/channel/326414-t-infra.2Fbootstrap/topic/Should.20Spellcheck.20check.20all.20files.3F/with/543227610

tidy now runs spellcheck (typos-cli) without adding `--extra-checks=spellcheck` option if the tool is already installed under ./build/misc-tools and the version is expected.
It will improve code quality without bothering engineers who doesn't want to use typos or who cleans up ./build directory frequently.
