Since <https://gcc.gnu.org/ml/gcc-patches/2015-02/msg00556.html> we
attempt to value-initialize in build_vec_init even when there's no
initializer but the type has a constexpr default constructor.  But
build_value_init doesn't work in templates, so I think let's avoid
this scenario; we'll go to the normal build_aggr_init path then.

Bootstrapped/regtested on x86_64-linux, ok for trunk and branches?

Hmm, we really shouldn't even be calling build_vec_init in a template, that builds up a lot of garbage that we'll throw away at the end of build_new.
