The sign information was not propagating into the rename map so only the last entry stored in the map could be retrieved for a given integer type. Propagating the sign information required an invasive change to ensure that all ValueRef (ValID) instances get the right sign information as well. Also, put in some assertions to ensure the RenameMap always gives us out the type that is expected.
