Adds micro benchmarks to measure low level (1) C memory reads and writes from Dart and (2) calls from Dart into C. This CL also adds a macro benchmark to measure overall performance using BoringSSL to digest data. The shared libraries are precompiled for Linux and live in cipd packages. The benchmarks run on all hardware architectures (with the exception of Linux'es hardfp on Arm32: https://github.com/dart-lang/sdk/issues/36309).

Run Existing Tests ================== See the output of ../tools/test.py --help for how to run tests. See also https://code.google.com/p/dart/wiki/Building#Testing for detailed examples. Create New Tests ================ See comments above factory StandardTestSuite.forDirectory in ../pkg/test_runner/lib/src/test_suite.dart for the default test directory layout. By default test-file names must end in "_test.dart", but some test suites, such as ./co19, subclass StandardTestSuite and override this default. See comments at the beginning of ../pkg/test_runner/lib/src/multitest.dart for how to create tests that pass by failing with a known error. For example, ... int x = "not an int"; //# 01: static type warning ... as part of a test will only pass the "--compiler dart2analyzer" test if the assignment generates a static type warning.
