Do not put incomplete CONSTRUCTORs into static memory
The CONSTRUCTOR_NO_CLEARING flag was invented to avoid generating a memset
for CONSTRUCTORS that lack elements, but it turns out that the gimplifier
can generate a memcpy for them instead, which is worse performance-wise,
so this prevents it from doing that for them.
* gimplify.c (gimplify_init_constructor): Do not put the constructor
into static memory if it is not complete.
