[Mesa-dev] [PATCH] i965: Don't try to print the GLSL IR if it has been freed

[Neil Roberts]

Since commit 104c8fc2c2aa5621261f8 the GLSL IR will be freed if NIR is
being used. This was causing it to segfault if INTEL_DEBUG=wm is set.
This patch just makes it avoid dumping the GLSL IR in that case.
