gdb: Convert language la_get_compile_instance field to a method

Browse source 
This commit changes the language_data::la_get_compile_instance
function pointer member variable into a member function of
language_defn.  Unlike previous commits converting fields of
language_data to member function in language_defn, this field is NULL
for some languages.  As a result I had to change the API slightly so
that the base language_defn class provides an implementation.

There should be no user visible changes after this commit.

gdb/ChangeLog:

	* ada-lang.c (ada_language_data): Delete la_get_compile_instance
	initializer.
	* c-lang.c (class compile_instance): Declare.
	(c_language_data): Delete la_get_compile_instance initializer.
	(c_language::get_compile_instance): New member function.
	(cplus_language_data): Delete la_get_compile_instance initializer.
	(cplus_language::get_compile_instance): New member function.
	(asm_language_data): Delete la_get_compile_instance initializer.
	(minimal_language_data): Likewise.
	* c-lang.h (c_get_compile_context): Update comment.
	(cplus_get_compile_context): Update comment.
	* compile/compile.c (compile_to_object): Update calls, don't rely
	on function pointer being NULL.
	* d-lang.c (d_language_data): Delete la_get_compile_instance
	initializer.
	* f-lang.c (f_language_data): Likewise.
	* go-lang.c (go_language_data): Likewise.
