I'm afraid this is too early, pass_ipa_increase_alignment is part of
all_small_ipa_passes list, those are run before the LTO streaming.
See cgraphunit.c (ipa_passes).
For OpenMP/OpenACC offloading, this has to run after the streaming,
which means either a pass in the all_regular_ipa_passes list, or much better
(I don't see any advantage of this being an IPA pass) some new pass that is
run very early in the all_passes list.
At which point I don't really see the benefit of moving this into a new file
either.
