Dan Gohman 58cfa3b137 Rename Instruction::isIdenticalTo to Instruction::isIdenticalToWhenDefined, ... and introduce a new Instruction::isIdenticalTo which tests for full identity, including the SubclassOptionalData flags. Also, fix the Instruction::clone implementations to preserve the SubclassOptionalData flags. Finally, teach several optimizations how to handle SubclassOptionalData correctly, given these changes. This fixes the counterintuitive behavior of isIdenticalTo not comparing the full value, and clone not returning an identical clone, as well as some subtle bugs that could be caused by these. Thanks to Nick Lewycky for reporting this, and for an initial patch! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@80038 91177308-0d34-0410-b5e6-96231b3b80d8		2009-08-25 22:11:20 +00:00
