* Move FindScalarValue from InstructionCombining.cpp to ValueTracking.cpp. WhileMatthijs Kooijman2008-06-161-0/+128
| | | | | | | | | | I'm at it, rename it to FindInsertedValue. The only functional change is that newly created instructions are no longer added to instcombine's worklist, but that is not really necessary anyway (and I'll commit some improvements next that will completely remove the need). llvm-svn: 52315

out of instcombine into a new file in libanalysis. This also teaches ComputeNumSignBits about the number of sign bits in a constantint. llvm-svn: 51863
