Detailed Description
Represents a prototype with parameter type info, e.g.
'int foo(int)' or 'int foo(void)'. 'void' is represented as having no parameters, not as having a single void parameter. Such a type can have an exception specification, but this specification is not part of the canonical type. FunctionProtoType has several trailing objects, some of which optional. For more information about the trailing objects see the first comment inside FunctionProtoType.
