This little patch corrects the result of decltype when applied to a
call to a function pointer, function reference, or member function
pointer.
Okay for mainline and 4.3?

* g++.dg/cpp0x/decltype12.C: New.

Just to be clear, the point of the complex handling of CALL_EXPR is that if you call a function that returns a reference, then the decltype of the call is the reference type, rather than the type without the reference? (I'm just checking why the answer is just TREE_TYPE (call_expr).)

The patch is OK, assuming that's approximately the explanation.
