* sparc/aes-encrypt-internal.asm, sparc/aes-decrypt-internal.asm:

Reduced frame size to 104 bytes, since we no longer need wtxt and
tmp on the stack.

+C I'm still slightly confused by the frame layout, specified in

+C However, Sun's cc generates a 104 byte stack frame for a function
+C with no local variables, so that should be good enough for us too.
