Grr! Sorry again for the second "typo" breakage in what should have been
a very simple patch. Although I can't reproduce the above failure on my
x86_64 box (or any of the other systems I tested this patch on), the RTL
check is diagnosing a real problem that I'm sorry I zoned on myself.
Fixed with the following patch. Committed to mainline as obvious as
revision 115076, after a full 3-stage bootstrap of the gcc/ directory
on x86_64-unknown-linux-gnu.
My apologies yet again for the breakage, and especially to Mark.

of XEXP to extract the operands of a MATCH_CODE rtx.
