Support NumberLong arithmetic in mongo shell and server JS

    Details

      Description

      Currently, NumberLongs are automatically cast to numbers when arithmetic is performed on them (courtesy of .toNumber()). This means that doing something like trying to subtract two NumberLongs returns a double-precision number, not a NumberLong. This causes a loss of precision, and this in turn means that hashed shard key values can't be manipulated in the shell.

      Supporting natural syntax like NumberLong("...") - NumberLong("...") isn't necessary, it would suffice to be able to do something like NumberLong("...").subtract(NumberLong("...")) and get back a NumberLong.
