Fix PR1850 by removing an unsafe transformation from VMCore/ConstantFold.cpp. Reimplement the xform in Analysis/ConstantFolding.cpp where we can use targetdata to validate that it is safe. While I'm in there, fix some const correctness issues and generalize the interface to the "operand folder". llvm-svn: 44817

Change tests from "opt %s" to "opt < %s" so that opt doesn't see the input filename so that opt doesn't print the input filename in the output so that grep lines in the tests don't unintentionally match strings in the input filename. llvm-svn: 81537
