0.pre7.79:

	added %COMPILER-DEFSTRUCT-generated inline expansions
		for type predicates
	removed predicate DEFUN from macroexpansion of DEFSTRUCT
		(so that now %DEFSTRUCT-generated closures and
		%COMPILER-DEFSTRUCT-generated inline expansions do
		everything)
	moved definitions of SPECIFIER-TYPE stuff later in
		early-type.lisp, after DEFSTRUCT VALUES-TYPE, so that
		the VALUES-TYPE-P call there can be inlined
