nit: This test no longer tests the "incoming" descriptor. Could we move the
content of this test down to "TestLinkageStubCall" a few lines below and then
just drop this test?

Done.

   Isolate* isolate = CcTest::InitIsolateOnce();
   Zone zone;
   ToNumberStub stub(isolate);
-  CompilationInfo info(&stub, isolate, &zone);
-  CallDescriptor* descriptor = Linkage::ComputeIncoming(&zone, &info);
+  CompilationInfo info("test", isolate, &zone, Code::ComputeFlags(Code::STUB));
+  CallInterfaceDescriptor interface_descriptor =
+      stub.GetCallInterfaceDescriptor();
+  CallDescriptor* descriptor = Linkage::GetStubCallDescriptor(
+      isolate, &zone, interface_descriptor, stub.GetStackParameterCount(),
+      CallDescriptor::kNoFlags, Operator::kNoProperties);
   CHECK(descriptor);
   CHECK_EQ(0, static_cast<int>(descriptor->StackParameterCount()));
   CHECK_EQ(1, static_cast<int>(descriptor->ReturnCount()));
   CHECK_EQ(Operator::kNoProperties, descriptor->properties());
   CHECK_EQ(false, descriptor->IsJSFunctionCall());
