This commit changes the language_data::la_lookup_transparent_type function pointer member variable into a member function of language_defn. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_data): Delete la_lookup_transparent_type initializer. * c-lang.c (c_language_data): Likewise. (cplus_language_data): Likewise. (cplus_language::lookup_transparent_type): New member function. (asm_language_data): Delete la_lookup_transparent_type initializer. (minimal_language_data): Likewise. * d-lang.c (d_language_data): Likewise. * f-lang.c (f_language_data): Likewise. * go-lang.c (go_language_data): Likewise. * language.c (unknown_language_data): Likewise. (auto_language_data): Likewise. * language.h (struct language_data): Delete la_lookup_transparent_type field. (language_defn::lookup_transparent_type): New member function. * m2-lang.c (m2_language_data): Delete la_lookup_transparent_type initializer. * objc-lang.c (objc_language_data): Likewise. * opencl-lang.c (opencl_language_data): Likewise. * p-lang.c (pascal_language_data): Likewise. * rust-lang.c (rust_language_data): Likewise. * symtab.c (symbol_matches_domain): Update call.
