bug in bitwise_arithmetic_shift_right

I found a bug in presto bitwise_arithmetic_shift_right function when shifting negative big int to the right beyond 63 digits. -- -- Result -2, -1, -9223372036854775808 -- select bitwise_arithmetic_shift_right(cast ('-9223372036854775808' as bigint), cast (62 as bigint)) , -- bitwise_arithmetic_shift_right(cast ('-9223372036854775808' as bigint), cast (63 as bigint)),
-- bitwise_arithmetic_shift_right(cast ('-9223372036854775808' as bigint), cast (64 as bigint)) -- this should give -1 it give -9223372036854775808 should be -2, -1, -1 i tested it on int, tiny int it works fine the problem is just with bigint input https://fburl.com/daiquery/dn4id08d

similarly bitwise_arithmetic_shift_right(cast ('9223372036854775807' as bigint), cast (64 as bigint)) -- this should give 0 not 9223372036854775807
