Apply and discard .linefile directives that appear within
the macro. For long macros, one might want to report the
line number information associated with the lines within
the macro definition, but we would need more infrastructure
to make that happen correctly (e.g. resetting the line
number when expanding the macro), and since for short
macros we clearly prefer reporting the point of expansion
anyway, there's not an obviously better fix here. */
