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.

We'd manually marked some of them hidden, but missed some. Do it in the perlasm
driver instead since we will never expose an asm symbol directly. This reduces
some of our divergence from upstream on these files (and indeed we'd
accidentally lose some .hiddens at one point).

∙ Some comments had the wrong function name at the beginning.
∙ Some ARM asm ended up with two #if defined(__arm__) lines – one from
the .pl file and one inserted by the translation script.

arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.
It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

See upstream's 9f0b86c68bb96d49301bbd6473c8235ca05ca06b. Generated by
using upstream's script in 5a3ce86e21715a683ff0d32421ed5c6d5e84234d and
then manually throwing out the false positives. (We converted a bunch of
stuff already in 91157550061d5d794898fe47b95384a7ba5f7b9d.)
This may require some wrestling with depot_tools to land in Chromium due
to Rietveld's encoding bugs, but hopefully that will avoid future
problems; Rietveld breaks if either old or new file is Latin-1.

This facilitates "universal" builds, ones that target multiple
architectures, e.g. ARMv5 through ARMv7.

This is a change from a while ago which was a source of divergence between our
perlasm and upstream's. This change in upstream came with the following comment
in Configure:
Note that -march is not among compiler options in below linux-armv4
target line. Not specifying one is intentional to give you choice to:
a) rely on your compiler default by not specifying one;
b) specify your target platform explicitly for optimal performance,
e.g. -march=armv6 or -march=armv7-a;
c) build "universal" binary that targets *range* of platforms by
specifying minimum and maximum supported architecture;
As for c) option. It actually makes no sense to specify maximum to be
less than ARMv7, because it's the least requirement for run-time
switch between platform-specific code paths. And without run-time
switch performance would be equivalent to one for minimum. Secondly,
there are some natural limitations that you'd have to accept and
respect. Most notably you can *not* build "universal" binary for
big-endian platform. This is because ARMv7 processor always picks
instructions in little-endian order. Another similar limitation is
that -mthumb can't "cross" -march=armv6t2 boundary, because that's
where it became Thumb-2. Well, this limitation is a bit artificial,
because it's not really impossible, but it's deemed too tricky to
support. And of course you have to be sure that your binutils are
actually up to the task of handling maximum target platform.

This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.
On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h
In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.
In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.
