These assume a new proc "is-option" as described in my first reply to
your patch.

Any one of the following would run the test only on an i?86 target when
-m64 isn't one of the command-line options.  Line breaks are added for
clarity.

  { dg-do run { target i?86-*-* } }
  { dg-require [dg-not [is-option "-m64"]] }

      or

  { dg-do run [dg-target-list target
                              [dg-and [istarget i?86-*-*]
                                      [dg-not [is-option "-m64"]]]] }

      or

  { dg-require [dg-and [istarget i?86-*-*]
                       [dg-not [is-option "-m64"]]] }

For a test that is run for a set of multiple targets but should be
skipped for i?86 when -m64 isn't a command-line option:

  { dg-do run { target xxx yyy zzz } }
  { dg-require [dg-not [dg-and [istarget i?86-*-*] [is-option "-m64"]]] }

I'm not sure about your third question; is this it?  The following
would add options when we're not on i?86 with -m64:

  { dg-options "options ..."
     [dg-target-list target [dg-not [dg-and [istarget i?86]
                                            [is-option "-m64"]]]] }

Yes, this is hard to follow, but ultimately it's more clear than using
a greater number of dg- commands to skip or xfail tests.
