RFR: Various fixed for system header

[Maurizio Cimadamore]

Hit Send too fast...

In StructImplGenerator we have this:

LayoutPath path = findAccessor(method, accessorKind);
             if (path != null) {
                 generateFieldAccessor(cw, method, accessorKind, path);
             }


So, in that case we swallow caes where we do not have layout for a given 
struct accessor. We should consider throwing in this case too.

Example:

NativeStruct("[ i32(get=bar) ](A)")
interface A extends Struct<A> {
     int foo(); //name mismatch
}
