Committed, MMIX: fix ld orphan placement bugs. Ok for 2.23?

I'd like to put this on the 2.23 branch too, please?
And <http://sourceware.org/ml/binutils/2012-09/msg00008.html>
(FAIL: gas/mmix/fb-2)?
Fixing orphan section bugs noticed in <http://gcc.gnu.org/PR54373>.
Testsuite additions obviously derived from that.
Committed to trunk.
Speaking of .tm_clone_table, isn't it needed to add a new output
section in elf.sc, like for .jcr, with a KEEP, or else the contents
will be GC:ed? Maybe section groups handle that these days?
ld:
* emultempl/mmo.em (mmo_place_orphan): Rewrite to also attach
orphan sections to .data and .bss output sections, not just .text.
When giving up on finding a suitable output section, attach to any
output section other than .MMIX.reg_contents, if it exists.
* scripttempl/mmo.sc: Move output debug sections to just before
.MMIX.reg_contents. Add .gnu.attributes. Add new . = . NOP
assignments and move end-of-section provide-symbols after them
to force the end-of-section symbols to the address after orphan
placement. Add SORT_NONE to .init and .fini sections.
ld/testsuite:
* ld-mmix/sec-1.d, ld-mmix/sec-3.d: Force end-of-section symbols
to be emitted and checked.
* ld-mmix/data-1.s, ld-mmix/orph-.d, ld-mmix/orph-awp.d,
ld-mmix/orph-d-a.d, ld-mmix/orph-d-awn.d, ld-mmix/orph-d-awp.d,
ld-mmix/orph-d-awpe.d, ld-mmix/orph-d.d, ld-mmix/orph-dc-ap.d,

ld-mmix/tm-ape.s, ld-mmix/tm-awne.s, ld-mmix/tm-awpe.s,
ld-mmix/tm-d-ap.s, ld-mmix/tm-d-awp.s, ld-mmix/tm-d.s,
ld-mmix/tm-e.s, ld-mmix/tm-orph1.s: New test files.
