[PATCH] D112276: [InstCombine] Fold `(c & ~(a | b)) | (b & ~(a | c))` to `~a & (b ^ c)`

Thinking more about it moving these patterns into AIC is not really a good option. I moved it there and tests I wrote pass. But it will not work on the original code produced by the FE. These tests are already simplified by the IC, and AIC works before the first IC run, so it will miss these.
