Chris Lattner d1b5e3fad9 now that all the pieces are in place, teach instcombine's ... simplifydemandedbits to simplify instructions with *multiple uses* in contexts where it can get away with it. This allows it to simplify the code in multi-use-or.ll into a single 'add double'. This change is particularly interesting because it will cover up for some common codegen bugs with large integers created due to the recent SROA patch. When working on fixing those bugs, this should be disabled. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@63481 91177308-0d34-0410-b5e6-96231b3b80d8		2009-01-31 08:40:03 +00:00
