[DAGCombiner] Reassociate the operands from (OR (OR(CMP1, CMP2)), CMP3) to (OR (OR(CMP1, CMP3)), CMP2)

[kmitropoulou]

Summary

This happens when CMP1 and CMP3 have the same predicate (or CMP2 and CMP3 have
the same predicate).

This helps optimizations such as the fololowing one:
CMP(A,C)||CMP(B,C) => CMP(MIN/MAX(A,B), C)
CMP(A,C)&&CMP(B,C) => CMP(MIN/MAX(A,B), C)

One of the comparisons is ne when we process the nodes of the DAG.

Should add a dag comment explaining the transform

no else after return

Seems reasonable, but I wonder how often this helps in real code.

Your patch does not handle swapped comparison conditions, e.g. reassociating an expression so that a<b can be combined with b>c. Doing that properly would make it much more complicated and I don't think it is worth it.

Your patch does not help if there is a tree of ANDs or ORs with more than three setcc nodes.

I ran the Vulcan game tests. The reassociateOpsCommutative() is called 115168 times and the proposed optimization is triggered 302 times. So, I will abandon the patch.

That seems worthwhile? Why abandon it?

I am sorry I restored it.
