Stop Gas from generating line info or address ranges for sections that do not contain code or are not loaded.
PR 26850
* dwarf2dbg.c (dwarf2_gen_line_info_1): Do not record lines in
sections that are not executable or not loadable.
(out_debug_line): Move warning message into dwarf2_gen_line_info_1.
* testsuite/gas/elf/dwarf2-20.s: New test.
* testsuite/gas/elf/dwarf2-20.d: New test driver.
* testsuite/gas/elf/elf.exp: Run the new test.
* testsuite/gas/elf/warn-2.s: Use the .nop directive.
