e189c86bc7 Consistently disable the Intel SHA Extensions code.
We haven't tested it yet, but it was only disabled on 64-bit. Disable it on
32-bit as well until we're ready to turn it on.

178a88c26f Synchronize sha512-x86_64.pl with upstream.
We missed 7eb9680ae1bf5dd9aeb61c401f2c3bd900ac9aeb. This is a no-op as we don't
set shaext right now anyway. This also includes some cosmetic changes to
minimize the diff with upstream. ("cosmetic". Upstream's perl doesn't like
spaces.)

09bdb2a2c3 Remove explicit .hiddens from x86_64 perlasm files.
This reverts the non-ARM portions of 97999919bb.
x86_64 perlasm already makes .globl imply .hidden. (Confusingly, ARM does not.)
Since we don't need it, revert those to minimize divergence with upstream.

97999919bb Hide all asm symbols.
We are leaking asm symbols in Android builds because the asm code isn't
affected by -fvisibility=hidden. This change hides all asm symbols.

This assumes that no asm symbols are public API and that should be true.
Some points to note:

In crypto/rc4/asm/rc4-md5-x86_64.pl there are |RC4_set_key| and
|RC4_options| functions which aren't getting marked as hidden. That's
because those functions aren't actually ever generated. (I'm just trying
to minimise drift with upstream here.)

In crypto/rc4/asm/rc4-x86_64.pl there's |RC4_options| which is "public"
API, except that we've never had it in the header files. So I've just
deleted it. Since we have an internal caller, we'll probably have to put
it back in the future, but it can just be done in rc4.c to save
problems.
