glsl: Don't choke when printing an anonymous function parameter

This is based on commit 174cef7fee7d400fc89a3ce68b7791d2aa3eb90f, but
the code is heavily changed.  The original commit modifies
ir_print_visitor::unique_name, but there is no such method in 7.10.
Instead, this code just modifies ir_print_visitor::visit(ir_variable
*ir) to "do the right thing" when ir_variable::name is NULL.
