11d0c4c098 Parsing, ASTs, and semantic analysis for the declaration of overloaded 
operators in C++. Overloaded operators can be called directly via
their operator-function-ids, e.g., "operator+(foo, bar)", but we don't
yet implement the semantics of operator overloading to handle, e.g.,
"foo + bar".

831c93f6c0 Parsing, representation, and preliminary semantic analysis of destructors. 
Implicit declaration of destructors (when necessary).

Extended Declarator to store information about parsed constructors
and destructors; this will be extended to deal with declarators that
name overloaded operators (e.g., "operator +") and user-defined
conversion operators (e.g., "operator int").

6f5431543a Implement C++ copy-initialization for declarations. There is now some

2fe9883a96 Standard conversion sequences now have a CopyConstructor field, to 
cope with the case where a user-defined conversion is actually a copy
construction, and therefore can be compared against other standard
conversion sequences. While I called this a hack before, now I'm
convinced that it's the right way to go.

Compare overloads based on derived-to-base conversions that invoke
copy constructors. 

Suppress user-defined conversions when attempting to call a
user-defined conversion.

0537942f3c Add implicitly-declared default and copy constructors to C++ classes, 
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).

1bb549685b Add header files to CMake build solution. It use globing so it doesn't need to be manually maintained, but it won't automatically detect a new header. I think this is a good compromise for the header files, since there presence in the solution is just an help for the user. Moreover, a new header is often introduced with a new cpp source file which need a makefile change, which will regenerate the solution and detect the new header.

2e8e604704 1. When a pointer to struct is used as an argument, GRSimpleVals::EvalCall() 
sets the whole struct to Unknown. Then we cannot assume the V passed to
   BindStruct() is always a CompoundVal. When it is an UnknownVal, we call
   BindStructToVal(UnknownVal).

2. Change the signature of InitializeStructToUndefined() to BindStructToVal()
   to reuse the code.

d50881c6a9 More fallout from r58501: primary fix is some more corrections to make 
the types for size_t and ptrdiff_t more accurate.  I think all of these
are correct, but please compare the defines for __PTRDIFF_TYPE__ and 
__SIZE_TYPE__ to gcc to double-check; this particularly applies to 
those on BSD variants, since I'm not sure what they do here; I assume 
here that they're the same as on Linux.

Fixes wchar_t to be "int", not "unsigned int" (which I think is 
correct on everything but Windows).

Fixes ptrdiff_t to be "int" rather than "short" on PIC16; "short" is an 
somewhat strange choice because it normally gets promoted, and it's not 
consistent with the choice for size_t.

26bee0b326 Implement basic support for converting constructors in user-defined

Notes:
  - Overload resolution for converting constructors need to prohibit

  - 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)

61956c460a Add support for parsing and representing C++ constructor declarations. 
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.
