Process non-static funcs with HandleTopLevelDecl().

Bug: 3092382
This fixes an issue where non-static functions were not properly being
annotated with zero-initializers for all RS object types. It turns out that
HandleTranslationUnit() occurs well after we have generated code for extern
functions (which is how this bug first showed up).
