Packed&aligned structs?

[leonardo-m]

Here they explain the need for repr(C) structs that are both aligned and packed:

Their solution:

#[repr(C, align(64))]
pub struct xregs_state(pub xregs_state_Inner);
#[repr(C, packed)]
pub struct xregs_state_Inner {
  // ...
}

Perhaps it's worth supporting this directly.
