Remove DefinedSynthetic.

With this we have a single section hierarchy. It is a bit less code,
but the main advantage will be in a future patch being able to handle

foo = symbol_in_obj;

in a linker script. Currently that fails since we try to find the
output section of symbol_in_obj.  With this we should be able to just
return an InputSection from the expression.
