[Bug target/36756] New: g++.dg/tls-3.C ICE with section-anchors, unit-at-a-time, no-toplevel-reorder

[janis at gcc dot gnu dot org]

Test g++.dg/gomp/tls-3.C started failing on powerpc-unknown-linux-gnu with an
ICE in rs6000_emit_move when the -O0 defaults were changed for
-funit-at-a-time, -fsection-anchors, and -ftop-level-reorder.  This smaller C
test:

__thread int i;
int
foo ()
{
  static __thread int k;
  return k;
}

gets the same ICE for earlier compilers back to 4.2.0 (when section anchors
were added) when compiled with "-funit-at-a-time -fsection-anchors
-fno-toplevel-reorder".
