I undestand it now. The problem is that fixup is missed for one gimple
body after statements was renumbered by analyzer. The reason is
confused check for has_gimple_body_p. We do not really get out of sync
between uids of functions and its clone, since we stream only clone, but
with the fact that stream in code expects uids to be continuously
increasing.
So apparenlty analyzer is first pass that does use UIDs of statements at
WPA time.
Sorry for taking so long time to understand this.
