[PATCH] fix for aarch64 sim adds64 bug

The set_flags_for_add64 function is computing carry out wrong.  It may
also be computing overflow wrong.  I replaced it with a copy of the
set_flags_for_sub64 function which is OK, just negating the tests for
value2.  I added a testcase to verify the change.  The testcase fails
without the patch, and works with the patch.

I also verified with a gcc C testsuite run.  The failures drop from
2710 to 2627.

The new testcase requires my previous patch to fix the
aarch64/testutils.inc file.
