compiler: Remove obsolete hidden_fields_are_ok code.

The language used to forbid assigning structs with hidden
fields, but that was changed before the Go 1 release.  At the
time the change was experimental, so I left the old code in
the compiler.  At this point it's clearly not experimental, so
this removes the unused code.
