ABI and the direction flag, that is it now assumes that the direction
flag is cleared at the entry of a function and it doesn't clear once

bit on the amd64/i386 for the signal handlers.
jhb@ noted that it might break old apps if they assumed DF == 1 would be
preserved in the signal handlers, but that such apps should be rare and
that older versions of gcc would not generate such apps.
