We set TYPE_HAS_USER_CONSTRUCTOR on the template type in lookup_using_decl,
but we didn't copy it to the instantiation.  Setting it in
one_inherited_ctor is too late, as that gets called after we decide whether
to set CLASSTYPE_LAZY_DEFAULT_CTOR.  This change affects other testcases as
well; the changes are fixes for the other inherited constructor tests as
well.

	* pt.c (instantiate_class_template_1): Copy
	TYPE_HAS_USER_CONSTRUCTOR.
	* class.c (one_inherited_ctor): Don't set it here.

IFN_DIV_POW2 currently requires all elements to be shifted by the
same amount, in a similar way as for WIDEN_LSHIFT_EXPR.  This patch
enforces that when building the SLP tree.

If in future targets want to support IFN_DIV_POW2 without this
restriction, we'll probably need the kind of vector-vector/
vector-scalar split that we already have for normal shifts.

We can't yet vectorise conditional internal functions whose boolean
condition is fed by a data access (or more generally, by a tree of logic
ops in which all the leaves are data accesses).  Although we should add
that eventually, we'd need further work to generate good-quality code.

Unlike vectorizable_load and vectorizalbe_store, vectorizable_call
wasn't checking whether the mask had a suitable type, leading to an
ICE on the testcases.
