Hi!
My earlier patches gimplify the simplest non-side-effects assumptions
into if (cond) ; else __builtin_unreachable (); and throw the rest
on the floor.
The following patch attempts to do something with the rest too.
For -O0, it actually throws even the simplest assumptions on the floor,
we don't expect optimizations and the assumptions are there to allow
optimizations.
I'd think we should trap on failed assume at -O0 (i.e. with
-funreachable-traps).
