Also remove the -Wtautological-constant-compare logic. I believe Clang
has since removed that problematic warning from -Wall and that check was
causing problems when we were embedded as a subproject in a project that
didn't set CMP0025.
(In that case, by the time our build file ran, the compiler had already
been detected and the damage done. This unfortunately means the next
Clang version check will hit the same issue, but let's deal with that
when we get there.)

2. If a C project statically links to our libssl.a, they'll use gcc

Most importantly, this version of delocate works for ppc64le. It should

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.

For now, this is the laziest conversion possible. The intent is to just
get the build setup ready so that we can get everything working in our
consumers. The intended end state is:
- The standalone build produces three test targets, one per library:
{crypto,ssl,decrepit}_tests.
- Each FOO_test is made up of:
FOO/**/*_test.cc
crypto/test/gtest_main.cc
test_support
- generate_build_files.py emits variables crypto_test_sources and
ssl_test_sources. These variables are populated with FindCFiles,
looking for *_test.cc.
- The consuming file assembles those variables into the two test targets
(plus decrepit) from there. This avoids having generate_build_files.py
emit actual build rules.
- Our standalone builders, Chromium, and Android just run the top-level
test targets using whatever GTest-based reporting story they have.
In transition, we start by converting one of two tests in each library
to populate the three test targets. Those are added to all_tests.json
and all_tests.go hacked to handle them transparently. This keeps our
standalone builder working.
generate_build_files.py, to start with, populates the new source lists
manually and subtracts them out of the old machinery. We emit both for
the time being. When this change rolls in, we'll write all the build
glue needed to build the GTest-based tests and add it to consumers'
continuous builders.
Next, we'll subsume a file-based test and get the consumers working with
that. (I.e. make sure the GTest targets can depend on a data file.)
Once that's all done, we'll be sure all this will work. At that point,
we start subsuming the remaining tests into the GTest targets and,
asynchronously, rewriting tests to use GTest properly rather than
cursory conversion here.
When all non-GTest tests are gone, the old generate_build_files.py hooks
will be removed, consumers updated to not depend on them, and standalone
builders converted to not rely on all_tests.go, which can then be
removed. (Unless bits end up being needed as a malloc test driver. I'm
thinking we'll want to do something with --gtest_filter.)
As part of this CL, I've bumped the CMake requirements (for
target_include_directories) and added a few suppressions for warnings
that GTest doesn't pass.
