[PATCH v2 0/2] gas: diagnostic improvements for macros

[Jan Beulich]

Since there were no comments / objections to v1, all v2 now does is cover
the remaining Arm testsuite failures (plus, of course, some re-basing, in
particular over additions to RISC-V testcase touched here as well). I
intend to commit this after another full run of testing, just in case some
new uses of .macro have appeared recently, but which I didn't notice going
in.

1: Arm: avoid unhelpful uses of .macro in testsuite
2: gas: re-work line number tracking for macros and their expansions
