IOFile: Require trivially copyable types

Browse Source 
Require ReadArray and WriteArray to be called with a trivially copyable
type.

ReadArray and WriteArray call std::fread and std::fwrite respectively.
These functions trigger undefined behavior when the objects are not
trivially copyable, so this adds that requirement to the callers.
