In ParseParenDeclarator match "D.setGroupingParens(true);" with another setGroupingParens call after the ')' is parsed.

Fixes this bug:
int (x)(0); // error, expected function declarator where the '(0)' initializer is

Implement support for C++ direct initializers in declarations, e.g. "int x(1);".
...
This is how this kind of initializers appear in the AST:
-The Init expression of the VarDecl is a functional type construction (of the VarDecl's type).
-The new VarDecl::hasCXXDirectInitializer() returns true.
e.g, for "int x(1);":
-VarDecl 'x' has Init with expression "int(1)" (CXXFunctionalCastExpr).
-hasCXXDirectInitializer() of VarDecl 'x' returns true.
A major benefit is that clients that don't particularly care about which exactly form was the initializer can handle both cases without special case code.
Note that codegening works now for "int x(1);" without any changes to CodeGen.

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).
