Thread language through c_type_print_args

Currently dwarf2read.c will pass the CU's language to
c_type_print_args -- but this doesn't affect all aspects of type
printing, because some code in c-typeprint.c refers to
current_language.

This patch threads the language through more of the type printing
code, adding an overload to c_type_print.  Some uses of
current_language remain, but now they are only in top-level functions.
