* ada-lang.c (ada_language_data): Remove
la_struct_too_deep_ellipsis initializer.
(ada_language::struct_too_deep_ellipsis): New member function.
* c-lang.c (c_language_data): Remove la_struct_too_deep_ellipsis
initializer.
(cplus_language_data): Likewise.
(asm_language_data): Likewise.
(minimal_language_data): Likewise.
* cp-valprint.c (cp_print_value): Update call to
struct_too_deep_ellipsis.

(auto_language_data): Likewise.
* language.h (language_data): Delete la_struct_too_deep_ellipsis
member variable.
(language_defn::struct_too_deep_ellipsis): New member function.
* m2-lang.c (m2_language_data): Remove la_struct_too_deep_ellipsis
initializer.Q
* objc-lang.c (objc_language_data): Likewise.
* opencl-lang.c (opencl_language_data): Likewise.
