gas DWARF2 test XPASSes

[Alan Modra]

git commit af2b318648 introduced a number of XPASSes.  This removes
them.  (It also introduces a FAIL on ft32-elf but the comment in the
.d file didn't adequately explain why the failure should be expected.)

	* testsuite/gas/elf/dwarf2-7.d: Remove most xfails.
	* testsuite/gas/elf/dwarf2-12.d: Likewise.
	* testsuite/gas/elf/dwarf2-13.d: Likewise.
	* testsuite/gas/elf/dwarf2-14.d: Likewise.
