Introduce partial_symbol::address

This introduces a partial_symbol::address method.  This method takes
an objfile argument.  This is necessary so that we can later relocate
a partial symbol at its point of use.  It also adds an accessor to
compute the unrelocated value; and a method to be used for setting the
field.

Note that the new method doesn't actually perform any relocation yet.
That will come in a subsequent patch.  However, the comments are
written to reflect the intended, rather than the temporary, semantics.
