[Bug rtl-optimization/31944] [4.1/4.2/4.3 Regression] Endless loop while building a 64-bit 2.6.20 kernel

So this has been failing since at least GCC 3.4.  And I see nothing in the
identified patch that is related to how CSE handles its values, so I suspect
this bug exists in older compilers as well (just needs another test case,
maybe).

And I still have no idea what is really going wrong here...
