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.

There was some uncertainty about what the code is doing with |$end0|
and whether it was necessary for |$len| to be a multiple of 16 or 96.
Hopefully these added comments make it clear that the code is correct
except for the caveat regarding low memory addresses.

This change makes the AEAD and EVP code paths use the same code for
AES-GCM. When AVX instructions are enabled in the assembly this will
allow them to use the stitched AES-GCM implementation.
Note that the stitched implementations are no-ops for small inputs
(smaller than 288 bytes for encryption; smaller than 96 bytes for
decryption). This means that only a handful of test cases with longish
inputs actually test the stitched code.

Since we pre-generate our perlasm, having the output of these files be
sensitive to the environment the run in is unhelpful. It would be bad to
suddenly change what features we do or don't compile in whenever workstations'
toolchains change or if developers do or don't have CC variables set.
Previously, all compiler-version-gated features were turned on in
https://boringssl-review.googlesource.com/6260, but this broke the build. I
also wasn't thorough enough in gathering performance numbers. So, flip them all
to off instead. I'll enable them one-by-one as they're tested.
This should result in no change to generated assembly.

Enable all compiler-version-gated features as they should all be runtime-gated
anyway. This should align with what upstream's files would have produced on
modern toolschains. We should assume our assemblers can take whatever we'd like
to throw at them. (If it turns out some can't, we'd rather find out and
probably switch the problematic instructions to explicit byte sequences.)
This actually results in a fairly significant change to the assembly we
generate. I'm guessing upstream's buildsystem sets the CC environment variable,
while ours doesn't and so the version checks were all coming out conservative.

SHA* gets faster. RSA and AES-GCM seem to be more of a wash and even slower
sometimes! This is a little concerning. Though when I repeated the latter two,
it's definitely noisy (RSA in particular), so we may wish to repeat in a more
controlled environment. We could also flip some of these toggles to something
other than the highest setting if it seems some of the variants aren't
desirable. We just shouldn't have them enabled or disabled on accident. This
aligns us closer to upstream though.

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.
