*unchecked-math* on macro-emitted arithmetic + local shadowing a bare native op

Browse source

Two general fixes shaken out by clojure.test.check's own suite (its splittable
PRNG mixes 64-bit longs and binds locals named min/max).

- *unchecked-math* now wraps arithmetic a macro emits. The analyzer rewrote a
  bare (+/-/*) to its wrapping unchecked-* under *unchecked-math*, but a macro's
  syntax-quote produces clojure.core/* (qualified), which was skipped — so e.g.
  test.check's mix-64 multiply grew to a bignum instead of a 64-bit long. The
  rewrite now also fires on the clojure.core-qualified form.
- A local binding named like a bare-emitted native op no longer shadows it. ops
  where native-ops maps the name to itself (+ - * / < > min max …) emit as the
  bare Scheme name; a local `max` emitted the same token, so
  (fn [max] (clojure.core/max …)) called the param. munge-name now prefixes such
  locals, like reserved words (derived from native-ops so they can't drift).

make test green (+1 corpus row, 0 new divergences), shakesmoke byte-identical.
One re-mint (analyzer + backend).
