The next patch will want to do language->print_type(type, ...), to print a type in a given language, avoiding a dependency on the current language. That doesn't work correctly currently, however, because most language implementations of language_defn::print_type call c_print_type without passing down the language. There are two overloads of c_print_type, one that takes a language, and one that does not. The one that does not uses the current language, defeating the point of calling language->print_type()... This commit removes the c_print_type overload that does not take a language, and adjusts the codebase throughout to always pass down a language. In most places, there's already an enum language handy. language_defn::print_type implementations naturally pass down this->la_language. In a couple spots, like in ada-typeprint.c and rust-lang.c there's no enum language handy, but the code is written for a specific language, so we just hardcode the language. In gnuv3_print_method_ptr, I wasn't sure whether we could hardcode C++ here, and we don't have an enum language handy, so I made it use the current language, just like today. Can always be improved later. Change-Id: Ib54fab4cf0fd307bfd55bf1dd5056830096a653b
