Adam Langley c2e415fe75 crypto: clarify licensing of OpenSSL asm code 
Several source files have been taken from OpenSSL. In some of them a
comment that "permission to use under GPL terms is granted" was
included below a contradictory license statement. In several cases,
there was no indication that the license of the code was compatible
with the GPLv2.

This change clarifies the licensing for all of these files. I've
confirmed with the author (Andy Polyakov) that a) he has licensed the
files with the GPLv2 comment under that license and b) that he's also
happy to license the other files under GPLv2 too. In one case, the
file is already contained in his CRYPTOGAMS bundle, which has a GPLv2
option, and so no special measures are needed.

In all cases, the license status of code has been clarified by making
the GPLv2 license prominent.

The .S files have been regenerated from the updated .pl files.

This is a comment-only change. No code is changed.

// SHA256/512 for ARMv8.
//
// Performance in cycles per processed byte and improvement coefficient
// over code generated with "default" compiler:
//
// SHA256-hw SHA256(*) SHA512
// Apple A7 1.97 10.5 (+33%) 6.73 (-1%(**))
// Cortex-A53 2.38 15.5 (+115%) 10.0 (+150%(***))
// Cortex-A57 2.31 11.6 (+86%) 7.51 (+260%(***))
// Denver 2.01 10.5 (+26%) 6.70 (+8%)
// X-Gene 20.0 (+100%) 12.8 (+300%(***))
// Mongoose 2.36 13.0 (+50%) 8.36 (+33%)
//
// (*) Software SHA256 results are of lesser relevance, presented
// mostly for informational purposes.
// (**) The result is a trade-off: it's possible to improve it by
// 10% (or by 1 cycle per round), but at the cost of 20% loss
// on Cortex-A53 (or by 4 cycles per round).
// (***) Super-impressive coefficients over gcc-generated code are
// indication of some compiler "pathology", most notably code
// generated with -mgeneral-regs-only is significanty faster
// and the gap is only 40-90%.
//
// October 2016.
//
// Originally it was reckoned that it makes no sense to implement NEON
// version of SHA256 for 64-bit processors. This is because performance
// improvement on most wide-spread Cortex-A5x processors was observed
// to be marginal, same on Cortex-A53 and ~10% on A57. But then it was
// observed that 32-bit NEON SHA256 performs significantly better than
// 64-bit scalar version on *some* of the more recent processors. As
// result 64-bit NEON version of SHA256 was added to provide best
// all-round performance. For example it executes ~30% faster on X-Gene
// and Mongoose. [For reference, NEON version of SHA512 is bound to
// deliver much less improvement, likely *negative* on Cortex-A5x.
// Which is why NEON support is limited to SHA256.]
