Proposal: Allow null coalescing operator for pointers

I realize that pointers in C# are not the most widely used construct but they exist and it would be nice if null coalescing operator worked for pointer types as well so we could write:
T *p1 = p2 ?? p3;
instead of:
T *p1 = p2 != null ? p2 : p3;

Copied from original issue: dotnet/roslyn#5869

This makes sense. If T *p1 = p2 != null ? p2 : p3; works so should T *p1 = p2 ?? p3;

Would #328 be of use here? I have already implemented that into Roslyn as a default-coalescing-operator. Haven't tried though whether it also works for pointers.

Update: my solution currently does not work with pointers. I'm going to adopt it. working with pointer also now.

Default value for pointer types is null so your proposal would fit here.

I've queued this to be considered by the LDM at #418.
