gas: restore Dwarf info generation after macro diagnostic adjustments
While 6fdb723799e2 ("gas: re-work line number tracking for macros and
their expansions") was meant to leave generated Dwarf as is, it really
didn't (and the testcase intended to catch that wasn't covering the case
which broke). Its adjustment to buffer_and_nest() didn't go far enough,
leading to the "linefile" directive inserted at the top to also be
processed later in the PR gas/16908 workaround (which clearly isn't
intended - it's being put there for processing during macro expansion
only). That unnoticed flaw in turn led me to work around it by a
(suspicious to me already at the time) conditional in as_where().
