I realize I'm late now with comments, seeing that the whole series was
committed, but still: While the v2 cover letter mentions mitigations
towards the size increase, using 64 bits uniformly still feels odd to
me. Those other size reductions are beneficial indepenently, and for
not overly large binaries it would imo be beneficial if they could get
away with just 32 bits of storage per function start offset. (Likely
this was discussed before,
