Question: For inc (which throws when given input Long/MAX_VALUE) there is an auto-promoting inc' and an unchecked-inc. quot now throws an exception in this case. Should there be an auto-promoting quot' and an unchecked-quot?

Patch clj-1254-v1.txt causes (quot Long/MIN_VALUE -1) to throw an exception due to overflow of the result, if the arguments are both long.
Unlike inc, which has auto-promoting version inc' and unchecked version unchecked-inc, there is no auto-promoting quot' and unchecked unchecked-quot. This patch does not add one.
Should quot' and unchecked-quot be added? If so, this ticket or a separate one?

Patch clj-1254-2.diff is identical to clj-1254-v1.txt except it applies cleanly to latest master. The only changes were in the context of the lines that were changed, due to a recent commit made.
