Chris Lattner 1e5665e6be Change a whole lot of diagnostics to take QualType's directly
instead of converting them to strings first.  This also fixes a
bunch of minor inconsistencies in the diagnostics emitted by clang
and adds a bunch of FIXME's to DiagnosticKinds.def.

Douglas Gregor 8e1cf608dc Implement initialization of a reference (C++ [dcl.init.ref]) as part
of copy initialization. Other pieces of the puzzle:

  - Try/Perform-ImplicitConversion now handles implicit conversions
    that don't involve references.
  - Try/Perform-CopyInitialization uses
    CheckSingleAssignmentConstraints for C. PerformCopyInitialization
    is now used for all argument passing and returning values from a
    function.
  - Diagnose errors with declaring references and const values without
    an initializer. (Uses a new Action callback, ActOnUninitializedDecl).
  
We do not yet have implicit conversion sequences for reference
binding, which means that we don't have any overloading support for
reference parameters yet.

Douglas Gregor cea4e74340 Some cleanups for the ambiguous derived-to-base conversion checks

Douglas Gregor 39c16d445e First non-embarrassing cut at checking for ambiguous derived-to-base
conversions.

Added PerformImplicitConversion, which follows an implicit conversion sequence
computed by TryCopyInitialization and actually performs the implicit
conversions, including the extra check for ambiguity mentioned above.

Douglas Gregor 5c407d9a9b Add support for conversions from a pointer-to-derived to a
pointer-to-base. Also, add overload ranking for pointer conversions
(for both pointer-to-void and derived-to-base pointer conversions).

Note that we do not yet diagnose derived-to-base pointer conversion
errors that stem from ambiguous or inacessible base classes. These
aren't handled during overload resolution; rather, when the conversion
is actually used we go ahead and diagnose the error.
