gas: Fix .debug_info CU header for --gdwarf-5
DWARF5 CU headers have a new unit type field and move the abbrev offset
to the end of the header.
gas/ChangeLog:
* dwarf2dbg.c (out_debug_info): Emit unit type and abbrev offset
for DWARF5.
* gas/testsuite/gas/elf/dwarf-4-cu.d: New file.
* gas/testsuite/gas/elf/dwarf-4-cu.s: Likewise.
* gas/testsuite/gas/elf/dwarf-5-cu.d: Likewise.
* gas/testsuite/gas/elf/dwarf-5-cu.s: Likewise.
* testsuite/gas/elf/elf.exp: Run dwarf-4-cu and dwarf-5-cu.
