Change compile_instance/compile_c_instance into classes This patch changes structs compile_instance and compile_c_instance into classes. Because of the nature of the change, there are a number of unavoidably mechanical changes buried in here, such as turning variable access of the POD struct into method calls, removing the struct keyword, and changing access of the plugin from "c_plugin->operation()" to "plugin ().operation ()". There is one "non-trivial" change associated with this patch, though. The type cache and symbol error maps have been moved into the base class, believing these facilities would be used other language implementations. [They are indeed re-used by C++.] gdb/ChangeLog: * compile/compile-c-support.c (c_get_compile_context): Use `new' instead of `new_compile_instance'. * compile/compile-c-symbols.c (compile_instance::insert_symbol_error): Update description.
