Why do you suggest alignment to only 8 bytes (not 16)? MOVAPS and friends
operate on 16 byte aligned data, and all non-x86 architectures are strictly
16byte aligned with no unaligned alternative possible.
I'd like to see that proposal extended to arbitrary power-of-2, and to
allow align(n) applied to structs/classes.
