Macros receive &form and &env

Browse source 
A macro body can now read &form (the call form) and &env (a map of the in-scope
local symbols), like Clojure. This is what core.logic's matche/defne use to tell
a pattern symbol that names an enclosing local from a fresh pattern var — so
locals-membero and the recursive checko in `matches` now compute correctly. The
suite reaches 535/2/0 (the last two are constraint reification ORDER, where the
constraint set is right but it is spliced from a set whose iteration order differs
from the JVM — a host set-ordering divergence, not a bug).

&form/&env are clojure.core dynamic vars bound around each expander call rather
than prepended params, so the macro calling convention is unchanged and the mint
stays consistent (the seed prelude is byte-identical; only the analyzer carries
the env into form-expand-1). macroexpand-1 passes an empty env.

corpus.edn: the ~@ unquote row is now a boolean compare (a bare clojure.core/
unquote-splicing symbol evaluates to an unbound var, not the symbol).
