ffi 1.6a: xfail — #objc_call with non-void return rejected today

Browse Source 
102/102 regression tests pass (+ffi-objc-call-04-primitive-returns
with xfail snapshot capturing today's diagnostic).

Pinned scenario: `[NSObject class]` — `#objc_call(*void)(null, "class")`.
Should return a non-null Class pointer once the lowering supports
non-void returns. Today the Phase 1.3 restriction trips with:

  #objc_call: only `void` return + (recv, selector) is lowered today;
  non-void / arg-bearing arities land in later phase-1 steps

The next commit (1.6b) introduces an `objc_msg_send` IR opcode that
bundles (recv, sel, args, ret_ty) and emit_llvm builds a per-call-
site LLVM function type, sharing one declared `@objc_msgSend`
symbol across return-type variants. Five primitive returns
(*void / bool / s32 / s64 / f64) get folded in across 1.6b–c.
