better -Wmeminit patch

This version ignores empty classes and checks for a nontrivial default ctor
instead of layout_pod_type.

This patch doesn't enable the warning unless explicity requested. I realise
that this warning is about enforcing style ("members should be initialised in
the mem-initializer-list not in the ctor body") but that's ok because it's my
preferred style, I just don't want the compiler to enforce other people's
preferred style ;)
