- recode back-to-back fwd_rnd() pairs to avoid two register moves.

- ditto for inv_rnd().

- optimize out lea 0(%ebp),%ebp

- remove two stray insns

# size aes-i586-asm.o.org aes-i586-asm.o
   text    data     bss     dec     hex filename
   5971       0       0    5971    1753 aes-i586-asm.o.org
   5905       0       0    5905    1711 aes-i586-asm.o

Overall, patch does not add and does not modify any insns, only removes a
handful of them.  However, speed difference is way below noise level.

Run-tested with tcrypt module.
