fdd8e9c8c7 Switch perlasm calling convention.
Depending on architecture, perlasm differed on which one or both of:

  perl foo.pl flavor output.S
  perl foo.pl flavor > output.S

Upstream has now unified on the first form after making a number of
changes to their files (the second does not even work for their x86
files anymore). Sync those portions of our perlasm scripts with upstream
and update CMakeLists.txt and generate_build_files.py per the new
convention.

This imports various commits like this one:
184bc45f683c76531d7e065b6553ca9086564576 (this was done by taking a
diff, so I don't have the full list)

Confirmed that generate_build_files.py sees no change.

BUG=14

dc0150fd22 aes/asm/aesni-x86[_64].pl update.
This addresses

- request for improvement for faster key setup in RT#3576;
- clearing registers and stack in RT#3554 (this is more of a gesture to
see if there will be some traction from compiler side);
- more commentary around input parameters handling and stack layout
(desired when RT#3553 was reviewed);
- minor size and single block performance optimization (was lying around);

(Imported from upstream's 23f6eec71dbd472044db7dc854599f1de14a1f48)

This one is best reviewed by verifying that
23f6eec71dbd472044db7dc854599f1de14a1f48^ in upstream has the exact same
versions of these files (we had no local diffs), so we can just copy them
wholesale.

bssl speed reports a wash on my Mac. If I keep running it, different ones win
each time.

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.

114a711f8b aes/asm/aesni-x86_64.pl: further optimization for Atom Silvermont.
Improve CBC decrypt and CTR by ~13/16%, which adds up to ~25/33%
improvement over "pre-Silvermont" version. [Add performance table to
aesni-x86.pl].

77b7e63311 Adjust stack pointer in AES-NI CBC decryption.
This change adjusts the stack pointer during CBC decryption. The code
was previously using the red zone across function calls and valgrind
thinks that the "unused" stack is undefined after a function call.
