Move capability checks in sha256-586.pl to C

This took a little restructuring because they were previously all one
big function. Some notes:

- label() and set_label() in x86 perlasm default to function-scoped. But
  static_label() marks a label as file-scoped, which is why "pic_point"
  and "K256" work.

- There's a pretty sizeable common preamble. I just copied it to each
  for simplicity. I'm pretty sure some of it is wasted, but it's
  definitely not all wasted, between loading parameters, setting up
  stack alignment, and saving the old stack location. But I'm not sure
  if all those 16 bytes are actually used.
