Put SA--SD in %eax--%edx, so the second byte can be accessed as
%ah-%dh. TD is not needed, SD can be reused. Use the register that
is saved for the outer loop counter, getting it off the stack.
* x86_64/aes-encrypt-internal.asm: Likewise.

* x86_64/aes.m4 (HREG, MOVE_HREG): New macros.
(XREG): Fixed bug in handling of %r8 and %r9.
(AES_ROUND): Use MOVE_HREG.

handling of comments.

* tools/sexp-conv.c (sexp_convert_item): Use sexp_put_soft_newline
to terminate comments, and modify indentation for the case that a
list starts with a comment.

* tools/output.c (sexp_output_init): Initialize soft_newline.
(sexp_put_raw_char): Clear soft_newline.
(sexp_put_newline): Check and reset soft_newline.
(sexp_put_soft_newline): New function.

* tools/output.h (struct sexp_output): Removed union with single
element, and updated all users. New attribute soft_newline.

non-static.
(yarrow256_force_reseed): Deleted function, use
yarrow256_slow_reseed instead. For backwards compatibility,
