Now that linux64-clang-11-macosx-cross doesn't need a macosx64-clang-*
to build, there is no circular dependency to avoid.

The new toolchain contains both aarch64 and x86_64 compiler-rts. We
could have a separate for each, but compiler-rt is small enough that
entirely separate toolchains is not warranted.

The llvm build system does support building a universal compiler-rt for
multiple platforms at once, but as far as I know it only supports doing
so with the same SDK, while we want to use separate SDKs for each, so
build the x86_64 compiler-rt separately.

We actually don't need the macosx-cross toolchain to build compiler-rt,
because building compiler-rt doesn't require compiler-rt (duh).

Only sanitizer builds require a native llvm-symbolizer executable.
Ideally, we'd build llvm-symbolizer from scratch, which would be faster,
but for now, let's go the easy route and just extract it from the
corresponding native clang builds.
We don't actually do anything with the llvm-symbolizer executable on
android builds, so we don't install it in $FINAL_TARGET, avoilding
the dependency on android builds (plus, we actually don't have an
android-native llvm-symbolizer, so even if it were already shipped, it
would be the wrong file).

In addition to the usual dot-release type of fixes, this also lets us drop a good amount of code that we had patched into our clang 11.

Bug 1683824 updated to the 0.2.14 tag, but that's patched in order to
publish to crates.io such that tiny-http is not patched anymore.
Unfortunately, that breaks sccache-dist, which is a known issue and will
eventually fixed when addressing
https://github.com/mozilla/sccache/issues/912.
So here we update to a corresponding version on master (the first that
bumps the version to the next number).

I was waiting for a better reason to do this, because the cbindgen
changes from 0.15.0 to 0.16.0 don't break trunk builds. But since
downstream has updated (see bug 1684180) and there's no reason not to,
let's do this to avoid future churn.

Since e10s-multi is going to be enabled by default, this gives us the ability
to run junit in a secondary, e10s-single configuration so that we can see them
both side-by-side for a little while, at least until we're settled in with the
e10s-multi configuration.

When building compiler-rt for macOS, its build system assumes the
compiler used is a native macOS clang, drops all the cmake C/C++ flags,
and adds its own.
Because we do need to pass `-target $target` (otherwise we end up with
ELF x86_64 objects) and `-mcpu=apple-a12` for the correct baseline for
arm64 macOS, and because there is unfortunately no cmake variable that
the compiler-rt build system will use, and because CMAKE_C*_COMPILER
need to be a program without arguments, we need to wrap the compiler.
While here, add `-v` to the ninja call to have more useful logs.

This patch enables ASan for rust code in the `linux64-asan/{debug,opt}` and `linux64-asan-fuzzing` build tasks. Since it is a `-Z` unstable flag, we'll move to the same `linux64-rust-nightly` toolchain that TSan builds use.
For the time being, the ASan Nightly Reporter builds are left alone, until we're more familiar with the perf impacts of this landing.

At this point it's pretty clear that we won't be reverting to clang-9.
This doesn't remove everything with clang-9 in the name. I did a mark-and-sweep GC by hand so this only removes unused entries. Some are still active, e.g. linux64-clang-9 is used to build a number of misc helper tools.

This requires tests to specify `python-3: true` in order to be run
with Python 3. When nothing is specified things work just like today,
so it's a more conservative change than the one in bug 1672181.
Obviously in the long term we will remove this and switch to Python 3
only, but this unblocks moving harnesses to py3 today.

Instantiating a wasm library duplicates a file descriptor for /dev/null 3 times to be used as input, output and error streams for the wasm sandboxed code. When a lot of sandboxes are created and destroyed, a lot of descriptors are duplicated and closed. While this should be fine, POSIX does not seem to happy with the opening and closing of many file descriptors --- this could perhaps be some strange interaction with Firefox's seccomp filters and cross-process file descriptor handling as it is difficult to repro this outside of firefox.
However, the simpler fix here was to just eliminate the duplication of /dev/null and return an error when input, output or error streams are accessed by wasm sandboxed code. This means calls to printf will fail, but no code I know off actually checks the int error code returned by printf and this change is certainly compatible with existing sandboxed components.

clang 12 (specifically https://reviews.llvm.org/D91379) made some refactorings to libc++ that exposed a problem in the MinGW headers. That has now been fixed upstream.
In the meantime the headers also gained definitions for ProcessPayloadRestrictionPolicy, so we can remove our workaround for that.
