This is so that we can avoid mutating state in sanitizerMutator, as
would be necessary if we only had a single bit for every sanitizer
together.
Test: Presubmits.

The 'fuzzer' sanitizer enables 'hwasan', which is not supported for Rust
static binaries. Make sure we skip applying this sanitizer to those
binaries.
Bug: 204776996
Test: SANITIZE_TARGET=fuzzer m <static_rust_executable>
Change-Id: I619cfab32b46c0811590973344eb5cdbe3f1a119
On HWASAN global sanitized builds, fuzz targets had hwasanFlags applied
twice. Rust only allows llvm-args flags to be passed in once however, so
this broke compilation.

This CL adds support for the MTE memtag_heap sanitizer. This is
controlled via inclusion of an ELF note.
Bug: 170672854
Test: Heap MTE-enabled Rust test binary triggers MTE

This CL adds Rust support for the SANITIZE_TARGET options.
This CL includes a couple small fixes to related to HWASAN, ASAN,
ensuring that the Never sanitize property is respected. Notably,
additional llvm-args are passed to ensure that HWASAN-ified Rust/C
interop works correctly.
Bug: 170672854
Bug: 204915322
Test: SANITIZE_TARGET globally applies hwasan to Rust targets

Structs embedding binaryDecorator (rust_test, rust_benchmark, rust_fuzz)
are binaries as well, but won't pass checks against *binaryDecorator,
such as the check in StaticExecutable().
Add a binaryInterface that can be checked instead to simplify these
checks and ensure we catch all binaries.
Bug: 170672854
Test: rust_test, rust_benchmark return true StaticallyLinked

Without `-C link-dead-code`, Rust fuzzers may fail to start fuzzing.
See the cargo-fuzz issue in the code comment for details. This patch
disables dead stripping for our fuzzers by default.
Bug: 193200135
Test: Flag emitted when building Rust fuzzers.
Test: Fuzzer runs on device.
Change-Id: I530de30e9a57db206bcbf3d2d3d371628eef8934
Refactors the vendor snapshot support to use the LinkableInterface
so that support can be extended to Rust. This CL does not add
vendor snapshot support for Rust; that is left for a follow-on CL.

HWASan for static Rust executables is not supported yet.
Bug: 180495975
Test: build local test app with HWASan

This flag causes a linkage error between rustc and our libclang_rt. We
can remove it for now and look into reintroducing it in the future.
We'd need to define 'thread_local uintptr_t __sancov_lowest_stack' to
support this. See https://reviews.llvm.org/D36839

libfuzzer-sys uses different flags in the 0.4.0 update, so update the
flags for rust_fuzz modules to align.
Test: m <example_fuzzer>
Change-Id: I0a1eb140a7843fdaf5266c05a1ecf6d3964e0f5e
Add a rust_fuzz module which builds a libfuzzer binary that enabes
asan+sancov. This relies on the libfuzzer-sys crate.
Bug: 147140513
Test: Local rust_fuzz example builds, fuzzes with asan+sancov.
