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.

It's unclear why .extern was being suppressed, it's also a little
unclear how the Chromium build was working without this. None the less,
it's causing problems with Android and it's more obviously correct to
make these symbols as hidden.

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.
