rustc 1.71.0 doesn't support any sanitizers for linux_musl_x86, disable
sanitizing for now.

This adds SCS as a sanitizer option in Rust.

'-Z sanitizer={hw}address' was not being passed if the fuzzer sanitizer
property was also set. Additionally, trying to use the fuzzer sanitizer

Rust libfuzzer flags have changed upstream, so update our set of flags.
This fixes the following fuzzer error:
ERROR: The size of coverage PC tables does not match the
number of instrumented PCs. This might be a compiler bug,
please contact the libFuzzer developers.

The logic is not 100% provably the same since HEAD was quite
confusing at some points, but I did make an effort to preserve
functional equivalence.
In case that effort was not enough, it should be pretty easy to
tweak the logic at HEAD since it's still quite malleable.

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.

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 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.

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.

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.

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.

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

Add a rust_fuzz module which builds a libfuzzer binary that enabes
