offload the work to hasConstantValue rather than do something more complicated (such handling mutually recursive phis) because (1) it is not clear it is worth it; and (2) if it is worth it, maybe such logic would be better placed in hasConstantValue. Adjust some GVN tests which are now cleaned up much further (eg: all phi nodes are removed). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@119043 91177308-0d34-0410-b5e6-96231b3b80d8
