[Bug middle-end/39447] ICE in create_data_ref with -O1 -floop-interchange

Hi,

I don't know who coded the overly complicated exclude_component_ref.
In the graphite branch we already cleaned up all this code, but in
trunk we still have it.

Attached is a patch that fixes the problem by looking at whether the
operand contains COMPONENT_REFs before calling the data reference
analysis.

I'm testing the patch on the gcc farm, and will send it to the gcc-patches
once it finishes regstrap.

Sebastian
