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.

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.
