Add BUILD(_HOST)?_FUZZ_TEST. These are tests that use LLVM's libFuzzer for testing with a sanitizer. Bug: http://b/22850550 Change-Id: I6eeaff7877b7dd0c30f8910c6f27f5278b27a83d

## A thin wrapper around BUILD_EXECUTABLE
## Common flags for fuzz tests are added.

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. Merged-In: Iaf0c7062f542dc6942b5349854f3d49267cac4a5 Change-Id: Iaf0c7062f542dc6942b5349854f3d49267cac4a5

Fix fuzzer builds. - Updates the fuzzer builds to use SANITIZE_TARGET='fuzzer' instead of 'coverage'. - Removed an old dependency that made fuzzer builds without ASan an error. - Fixed up the build flags to allow fuzzers to be built. Previously, the coverage flags were manually provided. As the toolchain has moved on, these flags are no longer compatible with libFuzzer, and so I've updated them to use the correct, compatible flags. Bug: 121042685 Test: With all patches in the bug merged, build a fuzzer using 'SANITIZE_TARGET=fuzzer mmma <your_fuzzer>'. Change-Id: I86e6a26d27c22b3622cf6ea8760f502f607df6f0

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. Change-Id: Ie6e6da9a202a258abf805dbdc8cdd3490fcb2406

Move fuzzers to include fuzz engine in pathname, default to 64-bit Old: /data/nativetest64/fuzzers/ID3_fuzzer/ID3_fuzzer New: /data/nativetest64/fuzzers/libFuzzer/ID3_fuzzer This allows having both the honggfuzz and libFuzzer variants built and flashed at the same time. It also means we don't have to rely on 'strings' to determine which type a given fuzzer is.

Add the honggfuzz binary as a dependency and keep symbols This way honggfuzz is rebuilt if it has changed, when building a fuzzer. Separately, keeping the symbols in the fuzzer binary is useful for crash triage. Change-Id: I2fc5ca64ccf66d084158580da74e5397aa61c250
