Reduce a lot of code duplication by implementing 
ConstantExpr::getWithOperandReplaced and ConstantExpr::replaceUsesOfWithOnConstant
 in terms of ConstantExpr::getWithOperands.  While we're at it,
make sure that ConstantExpr::getWithOperands covers all instructions: it was
missing insert/extractvalue.
