[Swift-devel] 'mapped type' terminology

The phrasing of this kinda excludes the idea that composite types might be 
mapped, which is not true at all...

The atomic types that are mapped to single files are what I initially 
called marker types; a better term was sought for that but 'mapped type' 
is not it in my opinion - being a mapped type or not is orthogonal to the 
atomic/composite distinction.
