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 syncs up with OpenSSL master as of
50ea9d2b3521467a11559be41dcf05ee05feabd6. The non-license non-spelling
changes are CFI bits, which were added in upstream in
b84460ad3a3e4fcb22efaa0a8365b826f4264ecf.

This makes it difficult to build against the NDK's toolchain file. The
problem is __clang__ just means Clang is the frontend and implies
nothing about which assembler. When using as, it is fine. When using
clang-as on Linux, one needs a clang-as from this year.
The only places where we case about clang's integrated assembler are iOS
(where perlasm strips out .arch anyway) and build environments like
Chromium which have a regularly-updated clang. Thus we can remove this
now.
Bug: 39
Update-Note: Holler if this breaks the build. If it doesn't break the
build, you can probably remove any BORINGSSL_CLANG_SUPPORTS_DOT_ARCH
or explicit -march armv8-a+crypto lines in your BoringSSL build.

Three modules were left behind in
I59df0b567e8e80befe5c399f817d6410ddafc577.
(Imported from upstream's c93f06c12f10c07cea935abd78a07a037e27f155.)
This actually meant functions defined in those two files were
non-functional. I'm guessing no one noticed upstream because, if you go
strictly by iOS compile-time capabilities, all this code is unreachable
on ios32, only ios64.
