Typed buffer format load/store operations with 16-bit elements require d16 support which was introduced in gfx8. These builtins previously had no required features at all, so they were accepted (and then crashed the backend) on targets without 16-bit support. Diagnose these in Sema, parallel to the image builtins. The manual verification here suprised me. The automatic builtin feature verification is enforced in codegen, which seems like a layering violation which should be fixed. Co-Authored-By: Claude (Opus 4.8) <noreply@anthropic.com>
