Daniel,
Your patch caused cpu2006/gcc to fail (results miscompare) at -O2
optimization level with 'test' dataset on ia32.


Uh, I was told by HJ that it actually fixes CPU2006.
Also, without a small testcase that doesn't involve CPU2006 (which i
don't have access to), i can't do anything.

Regardless, the code is correct and what there before was clearly
broken, so any cases it has broken are just latent bugs elsewhere.
