when appropriate.
Conversions for class types now make use of copy constructors. I've
replaced the egregious hack allowing class-to-class conversions with a
slightly less egregious hack calling these conversions standard
conversions (for overloading reasons).

reference-collapsing.
Implement diagnostic for formation of a reference to cv void.
Drop cv-qualifiers added to a reference type when the reference type
comes from a typedef.

conversions.
Notes:
- Overload resolution for converting constructors need to prohibit
user-defined conversions (hence, the test isn't -verify safe yet).
- We still use hacks for conversions from a class type to itself.
This will be the case until we start implicitly declaring the appropriate
special member functions. (That's next on my list)

etc more generic. For some targets, long may not be equal to pointer size. For
example: PIC16 has int as i16, ptr as i16 but long as i32.
Also fixed a few build warnings in assert() functions in CFRefCount.cpp,
CGDecl.cpp, SemaDeclCXX.cpp and ParseDeclCXX.cpp.

Notes:
- Constructors are never found by name lookup, so they'll never get
pushed into any scope. Instead, they are stored as an
OverloadedFunctionDecl in CXXRecordDecl for easy overloading.
- There's a new action isCurrentClassName that determines whether an
identifier is the name of the innermost class currently being defined;
we use this to identify the declarator-id grammar rule that refers to
a type-name.
- MinimalAction does *not* support parsing constructors.
- We now handle virtual and explicit function specifiers.

were being treated as type names for non-Objective-C files.
- Other lines are just because MinimalAction didn't have access to
the LangOptions.

BindDecl better describes what the function does:
- Bind the VarDecl to its memory region
- Bind the memory region to some initial value.

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.

- Do not allow expressions to ever have reference type
- Extend Expr::isLvalue to handle more cases where having written a
reference into the source implies that the expression is an lvalue
(e.g., function calls, C++ casts).
- Make GRExprEngine::VisitCall treat the call arguments as lvalues when
they are being bound to a reference parameter.

- GRExprEngine::VisitCompoundLiteral...
(1) visits the initializer list (generating ExplodedNodes)
(2) creates a CompoundMemRegion for the literal
(3) creates a new state with the bound literal values using
GRStateManager::BindCompoundLiteral
- GRStateManager::BindCompoundLiteral simply calls
StoreManager::BindCompoundLiteral to get a new store and returns a persistent
GRState with that store.
- BasicStore::BindCompoundLiteral simply returns the same store, as it
doesn't handle field sensitivity
- RegionStore::BindCompoundLiteral currently fires an assert (pending discussion
of how to best implement mappings for CompoundLiteralRegion).
