This means we can now skip building a 32-bit compiler-rt when building
clang itself, as well as the asan pdb files, which will be taken from
the compiler-rt artifact.

As of bug 1751824, the only remaining use of the 2-stages Windows clang
toolchain is for llvm-profdata in the generate-profile runs.
We don't need that to be built by clang itself (whereas it was desirable
to get compiler-rt from stage 2 before bug 1751824), so we can drop that
build to one stage only.
And because as of bug 1751839 we can start building stage 2 from a
separate stage 1 task, we do that for the Windows clang toolchain, like
we do for the Linux one.
Also, make the win64-clang-toolchain alias point to that stage 1 build,
like for Linux.

This reduces some code duplication and paves the way for modifying how
Mach loads modules.
The plan is to follow this up by making this function take a more fleshed out 'spec'
that maps command names to the files they're defined at and possibly more metadata.
Since this may affect how Mach works internally (e.g. with lazy loading in the roadmap),
it makes sense to move this logic inside the Mach class.

`MOZ_KNOWN_LIVE RefPtr<Foo> mFoo` is not treated as safe because its raw pointer
is referred with operators but they are not checked at handling `MOZ_KNOWN_LIVE`
annotation.
Additionally, when members marked as `MOZ_KNOWN_LIVE` are in the stack, they
are also not treated as safe, but they should be safe in most cases.
With these changes, `HTMLTableEditor.cpp` can get rid of a lot of
`MOZ_KnownLive` method calls.

Back when this was added, clang's default mode might have been c++11,
but it's not c++17, and we're effectively downgrading it (which
incidentally causes problems to build libc++).

It doesn't appear like the breaking changes will affect us.
Note that the taskcluster packages config wasn't updated because
`0.17.0` hasn't yet been deployed to the GitHub releases page.

This avoids needing clang-cl.exe on cross compilations. We could keep
Windows builds on having MIDL do the preprocessing, but that would be
a difference between native and cross builds, and it's better to avoid
that.

This allows to start building other toolchains, compiler runtimes, much
earlier, since we don't have to wait for a complete 4-stage-optimized
compiler to start these, while the output produced by clang is
presumably the same whether it's a stage 1 or a stage 4 clang.

It is currently enabled automatically because libxml2 is detected, but
we want to be sure it's not accidentally disabled.

`extra_targets` was used for the aarch64-linux compiler runtime, which
moved to a separate task in bug 1690757, and `android_targets` was used
for android compiler runtimes, which moved to separate tasks in
bug 1690973.
Using separate tasks is now the prefered way to build compiler runtimes,
os we won't need these options.

It was added for llvm-symbolizer, and at the time, it was required.
However, since [1] (shipped in llvm 12), llvm-symbolizer, msdia140.dll
is not used by default, only when passing the -dia command line option,
which we don't use.

A bunch of modern packages (`pytest`, `twisted`, `automat`) all need
`attrs==19.2.0` (or newer).
We _could_ bump `attrs` all the way to the modern `21.4.0` version, but
I'd like to defer that upgrade risk, since there's a
lot of backwards-incompatible changes and deprecations. So, lightly bump
it to `19.2.0`.
As part of bumping it, `pytest` is no longer compatible.
The earliest candidate that seems to be compatible is `pytest` 4.6.6,
which boasts in its release notes that it's resolved some deprecation
warnings against `attrs>=19.2.0`.
Once `pytest` was bumped, it needed a newer version of `pluggy`, which
itself has dependencies.
Since we're using hashes in `tox_requirements.txt`, all dependencies
needed to be hashed as well.

- AC_HAVE_FUNCS is an alias to AC_CHECK_FUNCS, so it is covered.
- Nothing uses HAVE___CXA_DEMANGLE, so we don't explictly set it,
although we do need the result of whether __cxa_demangle is supported.
- No moz.build uses MOZ_DEMANGLE_SYMBOLS, so we only `set_define` it.
- We leave dladdr in old-configure because it needs to move along other
dl* things.
- The hotfix for AC_CHECK_FUNC is however not needed for dladdr, so we
remove it.
- We replace the forced HAVE_LOCALECONV on Windows with a check shared
with all platforms.
