I've committed this patch on mainline to remove the adddi3 and subdi3
instructions for Xtensa. The recent thread about MIPS multiply/add made me
realize that there's no need for these on Xtensa, since the optabs.c code does
the same thing. Apparently, the optabs.c code does it better, too, since this
patch fixes several recent regressions in the testsuite.
