Detailed Description

TemplateSpecCandidate - This is a generalization of OverloadCandidate which keeps track of template argument deduction failure info, when handling explicit specializations (and instantiations) of templates beyond function overloading.

For now, assume that the candidates are non-matching specializations. TODO: In the future, we may need to unify/generalize this with OverloadCandidate.

NoteDeductionFailure()

void TemplateSpecCandidate::NoteDeductionFailure	(	Sema &	S,
		bool	ForTakingAddress
	)

Diagnose a template argument deduction failure.

We are treating these failures as overload failures due to bad deductions.
