1188: Support align and packed repr layout on structs r=dafaust a=dafaust

This is a start at handling the various layout options supported by Rust, beginning with `#[repr(align(N))]` and `#[repr(packed(N))]`, on structs and tuple structs.

There are several other layout options which remain to be supported such as `#[repr(C)]`, `#[repr(transparent)]`, combinations e.g. `#[repr(C, packed(2))]`, as well as layouts on union and enum types.

Fixes: #915
