Hi Richard,
This patch tries to move increase_alignment pass from small to regular ipa pass.
Does the patch look correct ?
Since we are only increasing alignment of varpool nodes, I am not sure
if any ipa
read/write hooks were necessary and passed NULL for them.
Cross-tested on arm*-*-*, aarch64*-*-*,
Bootstrap+test on aarch64-linux-gnu in progress.

Thanks,
Prathamesh
