Partially revert "ast: pack the ParseCommon struct" This reverts commit 1e6e5669c6229846830f0b497591de4e3cf588eb. It's probably safe, but let's not take any chances, as I don't have any esoteric arch to test on. But keep the ATTR in case it's ever useful. Signed-off-by: Ran Benita <ran234@gmail.com>
