Add an ABI testing framework. Dear reader, I must apologize in advance. This CL contains the following: - A new 256-line perlasm file with non-trivial perl bits and a dual-ABI variadic function caller. - C preprocessor gymnastics, with variadic macros and fun facts about __VA_ARGS__'s behavior on empty argument lists. - C++ template gymnastics, including variadic arguments, template specialization, std::enable_if, and machinery to control template argument deduction. Enjoy. This tests that our assembly functions correctly honor platform ABI conventions. Right now this only tests callee-saved registers, but it should be extendable to SEH/CFI unwind testing with single-step debugging APIs. Register-checking does not involve anything funny and should be compatible with SDE. (The future unwind testing is unlikely to be compatible.) This CL adds support for x86_64 SysV and Win64 ABIs. ARM, AArch64, and x86 can be added in the future. The testing is injected in two places. First, all the assembly tests in p256-x86_64-test.cc are now instrumented. This is the intended workflow and should capture all registers. However, we currently do not unit-test our assembly much directly. We should do that as follow-up work[0] but, in the meantime, I've also wrapped all of the GTest main function in an ABI test. This is imperfect as ABI failures may be masked by other stack frames, but it costs nothing[1] and is pretty reliable at catching Win64 xmm register failures. [0] An alternate strategy would be, in debug builds, unconditionally instrument every assembly call in libcrypto. But the CHECK_ABI macro would be difficult to replicate in pure C, and unwind testing may be too invasive for this. Still, something to consider when we C++ libcrypto. [1] When single-stepped unwind testing exists, it won't cost nothing. The gtest_main.cc call will turn unwind testing off.

Do a cursory conversion of a few tests to GTest. 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.
