This change replace the cmovq scheme with slightly faster SSE2 code.
The SSE2 code was first introduced in Go's curve25519 implementation.
See: https://go-review.googlesource.com/c/39693/
The implementation is basicly copied from the Go assembly.

The only place it is used is EC_KEY_{dup,copy} and no one calls that
function on an EC_KEY with ex_data. This aligns with functions like
RSAPublicKey_dup which do not copy ex_data. The logic is also somewhat
subtle in the face of malloc errors (upstream's PR 3323).
In fact, we'd even changed the function pointer signature from upstream,
so BoringSSL-only code is needed to pass this pointer in anyway. (I
haven't switched it to CRYPTO_EX_unused because there are some callers
which pass in an implementation anyway.)
Note, in upstream, the dup hook is also used for SSL_SESSIONs when those
are duplicated (for TLS 1.2 ticket renewal or TLS 1.3 resumption). Our
interpretation is that callers should treat those SSL_SESSIONs
equivalently to newly-established ones. This avoids every consumer
providing a dup hook and simplifies the interface.
(I've gone ahead and removed the TODO(fork). I don't think we'll be able
to change this API. Maybe introduce a new one, but it may not be worth
it? Then again, this API is atrocious... I've never seen anyone use argl
and argp even.)

I've done the test in a separate file on the assumption that aead_test

This introduces machinery to start embedding the test data files into
the crypto_test binary. Figuring out every CI's test data story is more
trouble than is worth it. The GTest FileTest runner is considerably
different from the old one:
- It returns void and expects failures to use the GTest EXPECT_* and
ASSERT_* macros, rather than ExpectBytesEqual. This is more monkey
work to convert, but ultimately less work to add new tests. I think
it's also valuable for our FileTest and normal test patterns to align
as much as possible. The line number is emitted via SCOPED_TRACE.
- I've intentionally omitted the Error attribute handling, since that
doesn't work very well with the new callback. This means evp_test.cc
will take a little more work to convert, but this is again to keep our
two test patterns aligned.
- The callback takes a std::function rather than a C-style void pointer.
This means we can go nuts with lambdas. It also places the path first
so clang-format doesn't go nuts.

Instead of a script which generates macros, emit static inlines in
individual header (or C files). This solves a few issues with the
original setup:
- The documentation was off. We match the documentation now.
- The stack macros did not check constness; see some of the fixes in
crypto/x509.
- Type errors did not look like usual type errors.
- Any type which participated in STACK_OF had to be made partially
public. This allows stack types to be defined an internal header or
even an individual file.
- One could not pass sk_FOO_free into something which expects a function
pointer.

We returned the wrong type, but with a typedef which made it void*. In
C++, void* to T* doesn't implicitly convert, so it doesn't quite work
right. Notably, Node passes it into sk_SSL_COMP_zero. The sk_* macros
only weakly typecheck right now, but a pending CL converts them to
proper functions.

Rather than comparing against both endpoints, subtract the minimum and
rely on unsigned wraparound to do both comparisons at once. This seems
to be slightly faster.
In addition, constant_time_lt_8 becomes much simpler if it can assume
that |a| and |b| have the same MSB. But we can arrange that by casting
up to |crypto_word_t| (which is otherwise happening anyway).

5c38c05b26 caused foo@GOTPCREL for
external foo to resolve to bcm_redirector_foo. This is morally
equivalent to using foo@PLT when a pointer to foo is needed. But this
does not work if foo is data. Notably, this ended up mangling
OPENSSL_ia32cap_P because it failed to recognize it as an symbol in the
library (but external to the module). It also mangles some things that
ASan emits.
(It also breaks non-NULL function pointer comparisons, but those are
silly.)
Instead, apply a variation of the OPENSSL_ia32cap_addr_delta trick that
works for the GOT. "addr_delta" is really weird, so I'm calling this an
"external relocation". This causes fprintf(stderr) to work and also
seems to keep ASan compiling. I was unable to reproduce the case that
5c38c05b26 added the bcm_redirector_foo
transform for.
Also tighten up the pattern. No need to reference a bit of memory twice
since we just loaded it into a register.
