Put data in .rodata and, rather than adr, use the combination of adrp :pg_hi21:
and add :lo12:. Unfortunately, iOS uses different syntax, so we must add more
transforms to arm-xlate.pl.
Tested manually by:
1. Use Android NDK r19-beta1
2. Follow usual instructions to configure CMake for aarch64, but pass
-DCMAKE_EXE_LINKER_FLAGS="-fuse-ld=lld -Wl,-execute-only".
3. Build. Confirm with readelf -l tool/bssl that .text is not marked
readable.
4. Push the test binaries onto a Pixel 3. Test normally and with
--cpu={none,neon,crypto}. I had to pass --gtest_filter=-*Thread* to
crypto_test. There appears to be an issue with some runtime function
that's unrelated to our assembly.
No measurable performance difference.
Going forward, to support this, we will need to apply similar changes to
all other AArch64 assembly. This is relatively straightforward, but may
be a little finicky for dual-AArch32/AArch64 files (aesv8-armx.pl).
Update-Note: Assembly syntax is a mess. There's a decent chance some
assembler will get offend.

This CL changes adds a ".hidden OPENSSL_armcap_P" statement to the
".comm OPENSSL_armcap_P" statements for the sha*-armv8.pl files,
similar to what was doen for the sha*-armv4.pl files in CL 3471.

These files are otherwise up-to-date with OpenSSL master as of
50ea9d2b3521467a11559be41dcf05ee05feabd6, modulo a couple of spelling
fixes which I've imported.
I've also reverted the same-line label and instruction patch to
x86_64-mont*.pl. The new delocate parser handles that fine.

This doesn't matter but reduces the diff for changes past it.
