Clojure loses quoted metadata on empty literals

meta on empty collections is lost:

user=> (meta '^:foo [])
nil   ;; expected {:foo true} as in:
user=> (meta '^:foo [1])
{:foo true}

This bug propagates to ^:const vars:

user=> (def ^:const foo ^:foo [])
#'user/foo
user=> (meta foo)
nil
user=> (meta @#'foo)
{:foo true}

Cause: As in CLJ-1093 Closed , empty collections are replaced with an EmptyExpr that loses meta

Proposed: Don't replace with EmptyExpr if meta is present.
