That looks good, but please `camelCase` the method names. Also, the method names sound like they mutate `this` rather than returning a value with the mutation in effect.
================
Comment at: clang/lib/AST/ASTContext.cpp:6885
+ .SetIsStructField()
+ .SetEncodePointerToObjCTypedef()),
+ FD, NotEncodedT);
----------------
These two uses can probably be hoisted up as a common operation, basically "do this for a component of the original type". `forComponentType()`, maybe?
