Unrolled build for rust-lang#134271

Rollup merge of rust-lang#134271 - adetaylor:feature-gate-test, r=wesleywiser

Arbitrary self types v2: better feature gate test

Slight improvement to the test for the `arbitrary_self_types_pointers` feature gate, to ensure it's independent of the `arbitrary_self_types` gate.

Part of rust-lang#44874
