Those extra memcpy calls look interesting.  I wonder whether it's because
g++ inlines small copies, or the dmd codegen produces a *lot* of them where
a better alternative could be used.

Also, I wonder whether making use of `= void` for local declarations that
don't have an initializer helps at all with anything performance-wise.
That at least should be a trivial change to magicport.
