In certain rare cases (such as those involving dereference of a
literal constant array of structs),
flatten_named_interface_blocks_declarations's rvalue visitor may be
invoked on an ir_dereference_record whose variable_referenced() method
returns NULL.
Check for this case to avoid a segfault.

out block_name {
float f;
} block_instance[2];
This allows Mesa to pass the piglit glsl-1.50 test:
