Pedro Alves 1c6fbf42e5 Always pass an explicit language down to c_type_print
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.
