Class-name symbols self-evaluate; extends? matches host classes; ISO_INSTANT

Browse source 
A slash-free dotted symbol with a Capitalized final segment (java.util.Map,
clojure.lang.Named, java.time.Instant) now self-evaluates to its name string
instead of resolving to nil — jolt models a class as its name, so a library
can extend a protocol to, or instance?-check, a host class jolt has no shim
for. hc-resolve-global classifies these as :class; the analyzer emits a const.

extends? now matches when either the query or the registered tag is a dotted
suffix of the other, so (extends? P java.util.Collection) finds the impl
extend registered under the canonical short tag.

Add DateTimeFormatter/ISO_INSTANT (UTC, trailing Z).

These unblock loading clojure.data.json, which dispatches JSONWriter on
java.util.Map/Collection/CharSequence/Instant and defaults a formatter to
ISO_INSTANT.
