ipa-split: Don't split returns_twice functions [PR106923]
As discussed in the PR, returns_twice functions are rare/special beasts
that need special treatment in the cfg, and inside of their bodies
we don't know which part actually works the weird returns twice way
(either in the fork/vfork sense, or in the setjmp) and aren't updating
ab edges to reflect that.
I think easiest is just to never split these, like we already never
split noreturn or malloc functions.
