Subject: Fix b/3427124. Adding the overloadable invokable feature. Reflect
 that type of invokables to Java.

1. Add __attribute__((overloadable)) support on the rs side for invokables. Requested by the Books team.
2. Add name mangling support and MangleContext.
3. Add the test P_overload.
4. This CL only affects Honeycomb SDK. It doesn't affect Final ROM.
5. This CL should go in at the same time with another CL on external/clang.git (to be done now.)
