Subject: [PATCH] linker: Silence GCC unused parameter warnings

linker.cpp:320:55: warning: unused parameter 'ir' [-Wunused-parameter]
    virtual ir_visitor_status visit_leave(ir_function *ir)
                                                       ^

linker.cpp:3368:49: warning: unused parameter 'ctx' [-Wunused-parameter]
 link_assign_subroutine_types(struct gl_context *ctx,
                                                 ^

Also make link_assign_subroutine_types static since it is only called
from this file.
