Record module type statistics Creates a build_system_stats.txt build artifact that contains statistics on how many BUILD_* modules are defined in a build. Also writes out information about the Soong module types sent from the Soong build.

Enhance coverage options to include those needed by Honggfuzz for coverage-driven fuzzing Test: make m Bug: 64903541 Change-Id: Ibb7eb126b6e68c03d0336606ec540a62a8e903d4 2017-08-21 23:07:42 +02:00			`LOCAL_CFLAGS += -fsanitize-coverage=trace-pc-guard,indirect-calls,trace-cmp`
Update fuzz_test makefile. Update the fuzz_test makefile to link against the new libFuzzer library and update the coverage flags to the new version. Test: built a fuzzer and verified correct linking.

Create sub-directory for fuzzers under nativetest. This CL changes BUILD_FUZZ_TEST to generate binaries in a sub-directory called fuzzers/ under the nativetest directory. This allows fuzzers to be distinguished from the other native tests and makes it easier to perform automated fuzz-testing.
