This does indeed look like PR42698. The pattern of backwards branching
indirect jumps is the same, and I'm pretty sure that this is the test case to
fix.

The issue is we have an invalid CFG:
{
int D.2137;
Invalid sum of incoming frequencies 1, should be 5000
M:
bb 3:
[LP 2] f ();
bb 4:
[LP 3] f ();
goto bb 6;
L:
L10: [LP 3]
goto bb 10 (L7);
