[Mesa-dev] [PATCH] glsl: Make ir_validate actually visit ir_if nodes.

[Kenneth Graunke]

There is no ir_hierarchical_visitor::visit(ir_if *) method, since ir_if
is not a leaf node.  Instead, there are visit_enter and visit_leave
methods.  Use visit_enter arbitrarily (either would work fine, though
visit_enter will catch errors sooner).

Found thanks to a warning emitted by Clang.
