patch
The issue is that need_to_predicate is not set and thus we do
/* Insert the predicate of the BB at the end of the BB
as this would reduce the register pressure: the only
use of this predicate will be in successor BBs. */
we only get to rewrite the call because need_to_rewrite_undefined. So
maybe we don't need to predicate this call at all?
Using GF_PLF_2 to mark predicated calls would be appropriate for example.
I'm testing the attached.
