Chez inc7: namespace :as aliases on the Chez-hosted analyzer

Browse source 
(require '[clojure.string :as s]) then s/foo crashed "Unknown class s": the
Chez analyzer resolved a qualified symbol's ns literally, and there was no
alias table (ns.ss jolt-ns-aliases was a stub, require a no-op). Add an alias
table + chez-register-spec! (parses [ns :as a]) in ns.ss; hc-resolve-cell now
resolves a qualified ns through it; compile-eval pre-registers a form's
require/use :as aliases before analysis (analysis precedes the runtime require,
so the runtime require staying a no-op is fine). The batched gate runner clears
the alias table between cases.

Zero-Janet corpus parity 2159 -> 2240, 0 divergences. spine-test 35/35.
