Functions
bool	isInStlNamespace (const Decl *D)
bool	isPointerLikeType (QualType QT)
const FunctionDecl *	getDeclWithMergedLifetimeBoundAttrs (const FunctionDecl *FD)
	Returns the most recent declaration of the method to ensure all lifetime-bound attributes from redeclarations are considered.
const CXXMethodDecl *	getDeclWithMergedLifetimeBoundAttrs (const CXXMethodDecl *CMD)
	Returns the most recent declaration of the method to ensure all lifetime-bound attributes from redeclarations are considered.
bool	isNormalAssignmentOperator (const FunctionDecl *FD)
bool	isAssignmentOperatorLifetimeBound (const CXXMethodDecl *CMD)
	Returns true if this is an assignment operator where the parameter has the lifetimebound attribute.

	Returns the lifetimebound attribute for the implicit this parameter, if it exists on the current type.
