[Bug rtl-optimization/51040] atomic_fetch_nand issue

Subject: [Bug rtl-optimization/51040] atomic_fetch_nand issue

NAND patchup arithmetic was missing the 2 stage AND then NOT operation.
Instead it was falling into the same sequence as every other operation and
trying to perform a binary operation on a NOT.

I managed to modify and existing testcase to trigger the bug without requiring
a configuration with RTL checking enabled.

Bootstrapped on x86_64-unknown-linux-gnu with no new regressions (pending
completetion of test run)

OK for mainline?
