-1. I think there's good arguments for using inline assembly on
platforms where we've done so historically, and where we have to support
old compilers without good support for intrinsics/builtins. But I see
very little reason for adding more such cases for newer platforms -
doing so correctly and efficiently is substantial work and fragile.
