--- Comment #6 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
/app/example.cpp:17:18: missed:   unusable type for last operand in
vector/vector shift/rotate.
/app/example.cpp:20:22: missed:   not vectorized: relevant stmt not supported:
_4 = 1 << _3;

Basically we can vectorize `bool<<i` but not `1<<i`.
