Add support for existential type recovery.
* interp/compiler.boot (compRecoverDomain): New. Split from
compRecoverGuard.
(compRecoverGuard): Split. Handle existential type recovery.
(compScheme): New. Register as compiler.
* interp/g-opt.boot (optLET*): New. Turn into LET-form if
appropriate. Register as backend transformer.
* interp/fnewmeta.lisp (|PARSE-Scheme|): New.
(|PARSE-Quantifier|): Likewise.
(|PARSE-QuantifiedVariableList|): Likewise.
(|PARSE-QuantifiedVariable|): Likewise.
* interp/metalex.lisp (KEYWORDS): Add 'forall' and 'exist' as new
keywords.
* interp/newaux.lisp: Register parser for expression schemes.
* algebra/any.spad.pamphlet (=$Any): If the underlying domain has
BasicType, use that equality operator.
(coerce$Any): If the underlying domain has CoercibleTo OutputForm
then use it.
