Should tight packing report a warning for string or hex literals?

[axic]

None of these report an issue currently:

        function f() pure public returns (bytes32) {
            return keccak256("hello");
        }
        function g() pure public returns (bytes32) {
            return keccak256(hex"001122");
        }

(Issue from #3956 (review))

I'm actually not sure we should have a warning here. The expectation would be that no padding is added. If that is the case, we do not need a warning.

This works as expected and we have tests for it.

For the record can you mention the test case names?

bytes_from_calldata_to_memory, sha3_multiple_arguments, and especially iterated_keccak256_with_bytes and keccak256_with_bytes.
