ADD missing clojure.core macros to clojure-mode font-lock declaration:

"amap" "areduce" "assert" "bound-fn" "comment" "definline" "definterface"
"defmethod" "defmulti" "defn-" "defonce" "defprotocol" "defrecord" "defstruct"
"deftype" "delay" "extend-protocol" "extend-type" "fn" "future" "gen-class"
"gen-interface" "import" "io!"  "lazy-cat" "lazy-seq" "let" "locking" "loop"
"memfn" "proxy" "proxy-super" "pvalues" "refer-clojure" "reify" "some->"
"some->>" "sync" "time" "vswap!"  "while" "with-bindings" "with-in-str"
"with-loading-context" "with-out-str" "with-precision"

remove duplicated non-special form font locks from special form def:
"let" "loop"

remove duplicated font locks symbols from clojure-mode-extra-font-locking

"amap" "areduce" "as->" "assert" "bound-fn" "comment" "delay" "extend-protocol"
"extend-type" "future" "gen-interface" "io!" "lazy-cat" "lazy-seq" "locking"
"memfn" "proxy" "proxy-super" "pvalues" "refer-clojure" "reify" "some->"
"some->>" "sync" "time" "while" "with-bindings" "with-in-str"
"with-loading-context" "with-out-str" "with-precision"
