3175fa5139 Properly deserialize ParamInfo of FunctionDecl. 
When allocating an array for ParamInfo, the "decl->getNumParams()" call was used, but this will return 0 since it checks ParamInfo (which isn't yet defined and is null).
The result was that ParamInfo got an array of zero length to hold the ParmVarDecls.

7d5fc7e28b Initial, rudimentary implementation of operator overloading for binary 
operators. For example, one can now write "x + y" where x or y is a
class or enumeration type, and Clang will perform overload resolution
for "+" based on the overloaded operators it finds.

The other kinds of overloadable operators in C++ will follow this same
approach. 

Three major issues remain:
  1) We don't find member operators
  2) Since we don't have user-defined conversion operators, we can't
  call any of the built-in overloaded operators in C++ [over.built].
  3) Once we've done the semantic checks, we drop the overloaded
  operator on the floor; it doesn't get into the AST at all.

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".

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.

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.
