afb9cae44d Add method MachineInstr::substituteValue() which substitutes 
one Value with another one in all operands and implicit references
of the machine instruction.

Also add method MachineOperand::getVRegValueOrNull().

12b9a2a7e6 Cleanup ConstantExpr handling: 
* Correctly delete TypeHandles in AsmParser.  In addition to not leaking
   memory, this prevents a bug that could have occurred when a type got
   resolved that the constexpr was using
 * Check for errors in the AsmParser instead of hitting assertion failures
   deep in the code
 * Simplify the interface to the ConstantExpr class, removing unneccesary
   parameters to the ::get* methods.
 * Rename the 'getelementptr' version of ConstantExpr::get to
   ConstantExpr::getGetElementPtr

79b72a8298 Added subclass ConstantExpr to represent expressions consructed from 
constants using operators such as cast, getelementptr, add, shl, etc.
Note that a ConstantExpr can be of any type, so classof() in most
other subclasses (that discriminate by type) have to check that it
is also not a ConstantExpr.   This is why isConstantExpr() is needed.

so don't make that argument const!
