Use C11 alignas in pg_atomic_uint64 definitions
They were already using pg_attribute_aligned. This replaces that withalignas and moves that into the required syntactic position. Thisends up making these three atomics implementations appear a bit moreconsistent, but shouldn't change anything otherwise.Reviewed-by: Chao Li <li.evan.chao@gmail.com>Discussion:https://www.postgresql.org/message-id/flat/46f05236-d4d4-4b4e-84d4-faa500f14691%40eisentraut.org
