Interesting information about a specific parameter that can't simply be reflected in parameter's type.
This is only used by FunctionProtoType but is in FunctionType to make this class available during the specification of the bases of FunctionProtoType.
It makes sense to model language features this way when there's some sort of parameter-specific override (such as an attribute) that affects how the function is called. For example, the ARC ns_consumed attribute changes whether a parameter is passed at +0 (the default) or +1 (ns_consumed). This must be reflected in the function type, but isn't really a change to the parameter type.
One serious disadvantage of modelling language features this way is that they generally do not work with language features that attempt to destructure types. For example, template argument deduction will not be able to match a parameter declared as T (*)(U) against an argument of type void (*)(attribute((ns_consumed)) id) because the substitution of T=void, U=id into the former will not produce the latter.

Is this parameter considered "consumed" by Objective-C ARC?
Consumed parameters must have retainable object type.
