core.contracts: fully passes, two general fixes

Browse source 
clojure.core.contracts (over core.unify) now runs its whole suite on jolt —
14/14 across contracts/constraints/with-constraints/provide tests. Two general
gaps fixed:

- Symbol and Keyword now report IFn (and Fn/Runnable/Callable) in the modeled
  class hierarchy, so a (class x)-dispatched multimethod with an IFn method
  matches a symbol or keyword, like the JVM (both implement IFn — they're
  callable). core.contracts' funcify* dispatches on (class constraint) and a
  bare predicate symbol must hit the IFn arm. Runtime, no re-mint.
- A live Var value spliced into a form by a macro (defcurry-from resolves a var
  and emits (~v l r)) now compiles: analyze treats a var-cell form as a
  :the-var reference by ns+name, the same node as (var ns/name), mirroring the
  existing spliced-namespace (~*ns*) case. analyzer.clj + host-contract.ss,
  re-mint (prelude stays byte-identical; only the analyzer image changes).

Listed in docs/libraries.md + the site.

make test green (+2 corpus rows, 0 new divergences), shakesmoke byte-identical.
