Argyrios Kyrtzidis 2b1ef227f5 Handle ambiguities between expressions and type-ids that occur inside parentheses, e.g.: 
sizeof(int()) -> "int()" is type-id
sizeof(int()+1) -> "int()+1" is expression.

Argyrios Kyrtzidis df788f4eea Found a subtle bug caused by an implicit enum-to-bool conversion (of the TentativeParsingResult enum). 
This was the motivation of the following changes:

-'TentativeParsingResult' enum is replaced by a 'TPResult' class that basically encapsulates the enum.
-TPR_true, TPR_false, TPR_ambiguous, and TPR_error enum constants are replaced by TPResult::True(), TPResult::False(), etc. calls that return a TPResult object.
-Also fixed the subtle bug in Parser::isCXXFunctionDeclarator (caught by the above changes as a compilation error).

Argyrios Kyrtzidis 2c7137d8d1 Resolve ambiguous C++ statements (C++ 6.8p1). 
'ParseTentative.cpp' implements the functionality needed to resolve ambiguous C++ statements, to either a declaration or an expression, by "tentatively parsing" them.
