21c60904ce PR7952: Make isa<> use the same logic as cast<>, so that they both work 
consistently.

0179e97723 Switch isa_impl from a function template to a class template with a 
static inline member function doit(). This enables the use of partial
specialization to override the last stage of the "isa" check.

3a3134ab12 use a c-style cast instead of reinterpret-cast, as sometimes the 
cast needs to adjust for a vtable pointer when going from base to
derived type (when the base doesn't have a vtable but the
derived type does).

9a0b165cb5 Revert r78424. 
In order for the changes in r78424 to work properly, cast_retty<X,Y> should return an object instead of a reference, and it's not clear that this approach has real advantages.

8b6d86df06 Modifications to dyn_cast/cast to make them work for objects too, instead of only pointers. 
The use case is if you have a wrapper class:

class Base {
  void *Ptr;
public:
  Base() : Ptr(0) { }
  operator bool() const { return Ptr; }
.....
}

and sub-wrappers that have exactly the same size:

class Sub : public Base {
public:
....
static bool classof(const Base*);
}

and in the code you would do:

void f(Base b) {
  Sub sub = dyn_cast<Sub>(b);
  if (sub) {
    ....
  }
}

bab6436b17 Check for NULL before traversing the isa<> type hierarchy checking with a 
NULL-based reference.

Note: Encountered this a few times on Tiger + gcc 4.0.1. Might just be a
platform-specific compiler issue, but it's good defensive programming in any
case.
