gas: re-arrange listing output for .irp and alike
Checks
Commit Message
It is kind of odd to have the expansions of such constructs ahead of
their definition in listings with macro expansion enabled. Adjust this
by pulling ahead the output of the definition lines, taking care to
avoid producing a listing line for (non-existing) line 0 when the source
is stdin.
---
According to my testing, with respective debugging code in place, the
conditional operator then isn't needed anymore in the invocation of
print_lines() that is being moved: As long as list->file->linenum is
non-zero, it and list->line are now always equal. I didn't make that
simplification right away though, as I fear I may be overlooking some
corner case. Unless I hear otherwise I intend to commit with that
adjustment.
The x86 testsuite adjustment goes on top of "x86: rework noavx512-1
testcase" [1]. If the change here is to go in first, the adjustment done
here would need folding into there (serving as a test of the new
behavior at the same time).
