Pass a frame to value_at_lazy and value_from_contents_and_address

This patch adds a 'frame' parameter to value_at_lazy and ensures that
it is passed down to the call to resolve_dynamic_type.  This required
also adding a frame parameter to value_from_contents_and_address.

Nothing passes this parameter to value_at_lazy yet, so this patch
should have no visible effect.
