I'd like to think that all the places where we apply semantics-sensitive
transformations and don't check for flag_wrapv are real bugs and should
be submitted to GNATs. I've fixed all those I'm aware of. However, I
really *hope* its not a requirement that I track down and fix all of the
remaining cases prior to getting this patch approved :>
