78cb7cd03d Add a class that is useful for hacking around linking problem due to 
pass implementations not being linked in when they are used if the
implementation is in a .a file.

  - Fighting with linking problem due to removing the ::ID elements.  Now the
    implementation .cpp files for analyses are not being included into gccas
    and friends because it is linking to the .a file and there is no explicit
    symbol reference to bring in the .o file.  The new IncludeFile hack is the
    result.

8f4f2153e5 - ConstantPointerRefs are now automatically removed from the module table 
when they are destroyed, which makes Constant::destroyConstant an actually
    useful external interface.  Expose these methods publicly.

    be used on any derived type constant safely.

 * 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.

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.

argument.  The difference is now that the #include of CommandLine.h does not
need to go into the header file as well.
