// M1.2 A.2c / A.3 — instance-method body lowering on sx-defined
// `#objc_class`.
//
// The Obj-C runtime invokes class methods via the IMP pointers
// wired up in M1.2 A.4. No sx-side call path drives lazy lowering,
// so the eager pass `lowerObjcDefinedClassMethods` walks the
// `objc_defined_class_cache` and force-lowers every bodied method
// after Pass 1 finishes.
//
// `*Self` substitution (A.2b) routes the param's pointee type to
// the hidden state-struct `__<ClassName>State`. `self.counter`
// then resolves as a plain struct field access — A.3's "free if
// types align". The IR snapshot pins the round-trip:
//
//   define internal void @SxFoo.bump(ptr __sx_ctx, ptr self) {
//       %gep = getelementptr inbounds { i32 }, ptr %self, 0, 0
//       %v = load i32, ptr %gep
//       %inc = add i32 %v, 1
//       store i32 %inc, ptr %gep
//       ret void
//   }
//
// IMP-trampoline emission (the C-ABI shim that the Obj-C runtime
// calls and that reads the `__sx_state` ivar) lands separately
// in M1.2 A.4 alongside class-pair init. Runtime dispatch
// (M1.2 A.7) stays gated until then.
