This commit improves the performance of ECDSA signature verification
(over NIST P-256 curve) for x86 platforms. The speedup is by a factor of 1.15x.
It does so by:
1) Leveraging the fact that the verification does not need
to run in constant time. To this end, we implemented:
a) the function ecp_nistz256_points_mul_public in a similar way to
the current ecp_nistz256_points_mul function by removing its constant
time features.
b) the Binary Extended Euclidean Algorithm (BEEU) in x86 assembly to
replace the current modular inverse function used for the inversion.
2) The last step in the ECDSA_verify function compares the (x) affine
coordinate with the signature (r) value. Converting x from the Jacobian's
representation to the affine coordinate requires to perform one inversions
(x_affine = x * z^(-2)). We save this inversion and speed up the computations
by instead bringing r to x (r_jacobian = r*z^2) which is faster.
The measured results are:

This makes running go test, etc., in util/fipstools/delocate work! This
adds a go_executable command to CMake like:
go_executable(delocate boringssl.googlesource.com/boringssl/util/fipstools/delocate)
which internally gets dependencies and whatnot so it behaves like usual
Go.
Update-Note: delocate has been rearranged a bit.

We currently write a mix of "if (FOO)" and "if(FOO)". While the former looks
more like a usual language, CMake believes everything, even "if" and "else", is
just a really really funny function call (a "command").
We should pick something for consistency. Upstream CMake writes "if(FOO)", so
go with that one.

Setting OPENSSL_NO_ASM skips enabling the “ASM” language in CMake.
However, the FIPS module fundamentally needs to build asm because
delocate works via textual assembly. Thus this combination is currently
broken with CMake.
This change ensures that support for building asm is enabled in CMake
for this combination.

Most importantly, this version of delocate works for ppc64le. It should
also work for x86-64, but will need significant testing to make sure
that it covers all the cases that the previous delocate.go covered.
It's less stringtastic than the old code, however the parser isn't as
nice as I would have liked. I thought that the reason we put up with
AT&T syntax with Intel is so that assembly syntax could be somewhat
consistent across platforms. At least for ppc64le, that does not appear
to be the case.

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.

Support for platforms that we don't support FIPS on doesn't need to be

buffering is enabled are left out because they aren't implementing any
cryptography and they use global r/w state, making their inclusion
painful.

The changes to delocate.go are needed because modes/ does things like
return the address of a module function. Both of these need to be
changed from referencing the GOT to using local symbols.
Rather than testing whether |ghash| is |gcm_ghash_avx|, we can just keep
that information in a flag.
The test for |aesni_ctr32_encrypt_blocks| is more problematic, but I
believe that it's superfluous and can be dropped: if you passed in a
stream function that was semantically different from
|aesni_ctr32_encrypt_blocks| you would already have a bug because
|CRYPTO_gcm128_[en|de]crypt_ctr32| will handle a block at the end
themselves, and assume a big-endian, 32-bit counter anyway.

Previously, inject-hash would run the FIPS module in order to trigger a
failure and then extract the calculated hash value from the output. This
makes cross-compiling difficult because the build process needs to run a
binary for the target platform.
This change drops this step. Instead, inject-hash.go parses the object
file itself and calculates the hash without needing to run the module.

This restores the original version of delocate.go, with the subsequent
bugfixes patched in. With this, the FIPS module builds with GCC and
Clang, with and without optimizations. I did patch over a variant of the
macro though, since it was otherwise really wordy.
Playing games with sections was a little overly clever and relied on the
compiler not performing a number of optimizations. Clang blew threw all
of those assumptions.
