What's the intent here? If the name is already 'call' you want to make it
'call'? Weird. I guess you want to map the user-defined 'call' method to
whatever we've decided to call the method we use to invoke closures. Maybe
introduce a constant for the RHS of the comparison to make it clearer?

Changed:
CLOSURE_INVOCATION_NAME is now initialized to Compiler.CALL_OPERATOR_NAME.
(which is set to "call").

The 'if' here and below has been removed.

     return '${privateName(lib, name)}\$$arity';
   }
 
   String instanceMethodInvocationName(LibraryElement lib, SourceString name,
                                       Selector selector) {
+    if (name == const SourceString("call")) name = CLOSURE_INVOCATION_NAME;
     // TODO(floitsch): mangle, while preserving uniqueness.
     StringBuffer buffer = new StringBuffer();
     List<SourceString> names = selector.getOrderedNamedArguments();
