Chandler Carruth a1f4697dba Revert r225053: Add an ArrayRef upcasting constructor from ArrayRef<U*> -> ArrayRef<T*> where T is a base of U. 
This appears to have broken at least the windows build bots due to
compile errors in the predicate that didn't simply supress the overload.
I'm not sure what the fix is, and the bots have been broken for a long
time now so I'm just reverting until Michael can figure out a fix.

Chandler Carruth 3ea985b375 [ADT] Add a remarkbly useful little helper routine to ArrayRef for 
checking whether the ArrayRef is equal to an explicit list of arguments.

This is particularly easy to implement even without variadic templates
because ArrayRef happens to be homogeneously typed. As a consequence we
can use a "clever" wrapper type and default arguments to capture in
a single method many arguments as well as *how many* arguments the user
specified.

Thanks to Dave Blaikie for helping me pull together this little helper.
Suggestions for how to improve or generalize it are of course welcome.
I'll be using it immediately in my follow-up patch. =D

David Majnemer 45647d8f74 ADT: Add a drop_back() helper to ArrayRef 
The slice(N, M) interface is powerful but not concise when wanting to
drop a few elements off of an ArrayRef, fix this by adding a drop_back
method.

Nick Kledzik 4d6d981297 Fix layering StringRef copy using BumpPtrAllocator. 
Now to copy a string into a BumpPtrAllocator and get a StringRef to the copy:

   StringRef myCopy = myStr.copy(myAllocator);
