[PATCH 0/5] gas: diagnostics for macros and some tidying

[Jan Beulich]

The primary goal here is the last patch, but a few other, easier
things were noticed while getting there. The series is slightly
RFC, and the last patch isn't covering all testsuite fallout yet
for Arm, for it being simply too many tests which need touching
(and hence I'd like to defer doing that work until I know there
are no fundamental objections).

1: gas: avoid inserting extra newline in buffer_and_nest()
2: gas: squash (some) .linefile from listings
3: gas: add Dwarf line number test for .macro expansions
4: Arm: avoid unhelpful use of .macro in testsuite
5: gas: re-work line number tracking for macros and their expansions
