When enabling neon (--with-fpu=neon, or when the C++ compiler defaults
to use neon), we pass +neon as a target feature to the rust compiler.
That enables neon in rust, which is the default with the
thumbv7neon-linux-gnueabihf rust target, but not the default for the
armv7-unknown-linux-gnueabihf rust target.
ARM processors may have various different FPUs, with different number of
registers. On ARMv7, there are FPUs with 16 registers and FPUs with 32
registers. NEON requires 32 registers.
Because the common denominator for ARMv7 is 16 registers, the
armv7-unknown-linux-gnueabihf rust target defaults to 16 registers,
although by enabling neon, we're guaranteed the processor will have 32.
But while the rust compiler keeps limited to 16 registers, it also hits
a wall while compiling the hyper crate, where it finds it doesn't have
enough registers (which in itself can be considered a bug).
Since enabling neon means there are 32 registers available, it makes
sense to tell the compiler to lift the restricted use of FPU registers,
and that's what the `-d16` target feature does.
That's the default for the thumbv7neon-linux-gnueabihf rust target, so
nothing is changed, there, and fixes things for the
armv7-unknown-linux-gnueabihf rust target.

There is a big difference between generated source files that are built
directly, and those that are only included.
In the latter case, the build system won't know the files that does the
including depends on the generated source. So those sources do need to
be built during the export tier.
But in the former case, the build system has all the dependency
information it needs, and, while these generated sources are currently
built as part of the export tier, they don't actually need to be. We're
going to change that, and in preparation, we rename included files so as
to be more clearly identified.

This follows the model set down for EME artifacts:
- a new tier is added that uses a new Python build action to fetch and
artifacts
- the action unpacks the fetched artifacts and moves specific inputs
into places expected by the build and packager
- in automation, MOZ_ARTIFACT_TASK* is used to ensure the artifacts
come from the correct tasks
In this case, the artifact fetching is done entirely in a new Python
build action that internally uses `mach artifact install --job ...`.
The action also verifies that the fetched artifacts are compatible and
that we're not assembling a fat AAR that is nonsensical. The specific
inputs are not used in the Fennec APK that is produced; they're only
used in the GeckoView AAR that is produced.
The artifact fetching itself required tweaking to fetch only
`target.maven.zip` artifacts and to not unpack them.
The specific inputs used are the native libraries (libs/$ARCH/*.so)
and the architecture-specific preference files ($ARCH/greprefs.js and
defaults/pref/$ARCH/geckoview-prefs.js). None of these inputs are
impacted by l10n.

We weren't honoring the case where the library features differ from the tests
features (situation which my previous patch does).
We were incorrectly overriding `rust_feature_flags`, which of course ended up
with a working rusttests with my patches, but a bunch of negative leaks :)
Name the test features differently so that they don't affect the regular library
features.

We add to `GARBAGE_DIRS` for Rust programs because Rust programs
currently do not share compilation artifacts with Rust libraries (as our

compilation artifacts between the two is a non-starter).

Summary:
- ICU no longer supports removing resource files manually, instead the new data
filter builder needs to be used.
- This includes test data, which also must be preserved in ICU 64.
- umutex.h contains an implicit call to `new` in ICU64 which needs to be allowed
in check_vanilla_allocations.py.
- Drive-by: Make ICU with multiple jobs for faster rebuilds.

The current setup uses different ways for different platforms, with
different workarounds, even using extra configuration items for Windows.
Now that there can't be a difference between the host per the build
system and the host per rust, we can get rid of those configuration
items, and use a more common infrastructure.
We cannot, however, avoid using wrapper scripts, because per-target rust
link-arg flags don't work up great.
The downside is that multiplies the number of wrappers, as we now have
to have a different one for host and target, and then we have .bat files
and shell scripts for, respectively, Windows hosts, and other hosts.

On one-go MOZ_PGO builds, it's generally not wanted to do LTO during the
profile-generate phase. And the build system doesn't really support
different build options between both phases in this case, so we relied
on MOZ_PROFILE_GENERATE to disable the LTO flags.
However, in standalone profile-generate builds, if --enable-lto is
passed explicitly, the build should respect that choice.
So instead of checking MOZ_PROFILE_GENERATE to disable the LTO flags,
we disable them when MOZ_LTO is not set, and we force it to be disabled
during the profile-generate phase of one-go MOZ_PGO builds.

This patch adds detection for when icecream is in use to build telemetry.
icecream is commonly enabled in two ways: by either setting CC/CXX to point
to icecream's cc/c++ symlinks, or by setting adding
mk_add_options 'export CCACHE_PREFIX=icecc' to a mozconfig when also using
ccache. For the former, this patch adds a simple configure check to see
if CXX is a symlink to a file named 'icecc'. For the latter this patch adds
CCACHE_PREFIX as a configure subst to capture the value.
We don't currently have a facility for writing telemetry tests that depend on
configure values. Local manual testing shows that it does work as expected.

Consequently, this removes:
- MOZ_LIBPRIO, which is now always enabled.
- non_msvc_compiler, which is now always true.
- The cl.py wrapper, since it's not used anymore.
- CL_INCLUDES_PREFIX, which was only used for the cl.py wrapper.
- NONASCII, which was only there to ensure CL_INCLUDES_PREFIX still
worked in non-ASCII cases.
This however keeps a large part of detecting and configuring for MSVC,
because we still do need it for at least headers, libraries, and midl.
