I'll try to implement it tomorrow, currently don't see why
your idea wouldn't work. I haven't actually been able to write
a testcase that switches from cold to hot btw., not sure if that
is because I just didn't try very hard or because gcc never emits
it. -freorder-blocks-and-partition is certainly terribly undertested
(though I wonder if anybody actually uses it, e.g. given that
EH for it has been broken for years).
