*more* alignment problems

[Richard Kenner]

    Maybe for a change this extensive you should have bootstrapped more than
    just one target.

I only really *have* one target easily accessible to me now.

    What unit is ALIGN supposed to have for store_field?  In at least one
    case it's being called with alignment in bits.

It's supposed to have bits *everywhere*.

    That value gets passed to store_bit_field which expects alignment in bytes
    according to its comment.

I thought I fixed the comment.

Let me review.
