Unrolled build for rust-lang#116452

Rollup merge of rust-lang#116452 - cjgillot:noassert-erased, r=oli-obk

Do not assert that hidden types don't have erased regions.

cc rust-lang#116306

`args` can have erased regions.
In the linked issue, this is reached by computing whether a large type is `Freeze` to compute its ABI.

I do not have a minimized test to include.
