Updated 2021-09-21 after test harness fixes.

The failures are reported from crates/stdarch-test/src/lib.rs:162 and cover core_arch aarch64 and arm_shared NEON tests. Start by reproducing the disassembly assertions on macOS aarch64 and comparing the expected instruction names with the emitted output. Done means the affected tests correctly recognize the target instructions and pass.
