implicit conversion sequence, check the validity of this conversion
and then perform it.

Tests and drivers updated, still need to shuffle dirs.

the type of the enumeration once the enumeration has been defined.
Fix the overloading test-case to properly create enums that promote
the way we want them to.
Implement C++0x promotions from enumeration types to long
long/unsigned long long. We're using these promotions in Carbon.h
(since long long is a common extension).

- Allows definitions of overloaded functions :)
- Eliminates extraneous error messages when we have a definition of a
function that isn't an overload but doesn't have exactly the same type
as the original.

ImplicitConversionSequence and, when doing so, following the specific
rules of [over.best.ics].
The computation of the implicit conversion sequences implements C++
[over.ics.ref], but we do not (yet) have ranking for implicit
conversion sequences that use reference binding.

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.

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.

conversions (e.g., comparing int* -> const int* against
int* -> const volatile int*); see C++ 13.3.3.2p3 bullet 3.
Add Sema::UnwrapSimilarPointerTypes to simplify the control flow of
IsQualificationConversion and CompareQualificationConversion (and fix
the handling of the int* -> volatile int* conversion in the former).
