Relax vect_check_scalar_mask check
When the mask is not a constant or external def there's no need to
check the scalar type, in particular with SLP and the mask being
a VEC_PERM_EXPR there isn't a scalar operand ready to check
(not one vect_is_simple_use will get you). We later check the
vector type and reject non-mask types there.
* tree-vect-stmts.cc (vect_check_scalar_mask): Only check
the scalar type for constant or extern defs.
