[Bug tree-optimization/32139] New: [4.1 Regression] ICE in mark_operand_necessary

[jakub at gcc dot gnu dot org]

int foo (void);
int bar (void) __attribute__((const));

int
test (int x)
{
  int a = (x == 10000 ? foo : bar) ();
  int b = (x == 10000 ? foo : bar) ();
  return a + b;
}
ICEs in mark_operand_necessary.
3.4.x works and so does 4.2 and trunk.

Related to in PR29382 described common_pointer_type, but perhaps not just that.
