Changes in the JDK source will be required. Namely, we need to call 
another function to find whether a struct is a nested anonymous struct, 
as well as update some of the type/cursor kind enums. There are also 
other things like support for IncompleteArray field types that was fixed 
in LLVM 9 and we can start taking advantage of that.
