Patch updated:
1. Corrected DAGCombiner 'arcp' optimization to only trigger for the reassociation division case, not the estimate cases.
2. Updated PowerPC test case that uses that optimization (x86 still doesn't have it); worked around PR23172 by putting the 'arcp' versions of the tests before the unsafe-fp-math versions.
