Yeah, something along that line would be needed. The issue is that
the partial value is not available (as in: it doesn't have a SSA name)
and thus there is nothing to CSE the load

Certainly removing the alignment is not going to fly - we'd generate
very bad code for strict-align targets for initializing packed
patch fixes it (changing the first ldr instruction to an ldar
in this case). Full AArch64 assembly listings below.
I've also written a blog post on this subject in the hope of clarifying the
