d7231ac523 PHINode::hasConstantValue should never return the PHI itself, even if the
PHI is its only operand.

b3b48e11da Use the bool argument to hasConstantValue to decide whether the client is
prepared to deal with return values that do not dominate the PHI.  If we
cannot prove that the result dominates the PHI node, do not return it if
the client can't cope.

a83ba0f5c9 Fix a fixme in CondPropagate.cpp by moving a PhiNode optimization into
BasicBlock's removePredecessor routine.  This requires shuffling around
the definition and implementation of hasContantValue from Utils.h,cpp into
Instructions.h,cpp

64001d0a13 Allow these methods to take a generic Value* to simplify clients. Use
const_cast instead of c casts.

b12261ac69 Merge InstrTypes.cpp into this file
Adjust to changes in the User class, operand handling is very different.
PHI node and switch statements must handle explicit resizing of operand
lists.

ReturnInst constructed is the same as if NULL was passed instead of
the void value.
