One of the things bug 1567616 did was to change how .cargo/config is
preprocessed, from it happening during configure to it happening during
the build. And to make things happen properly, dependencies were added
on the rust targets to ensure the .cargo/config file is created before
they run.
Unfortunately, that changed the order in which Make would run all the
targets while recursing for the compile tier, when the file doesn't
exist first. So instead of starting the compile tier with rust targets,
it would start with most C++, then do rust... which we know to make
builds slower overall because of the need to wait for those rust builds
to finish which C++ has all been dealt with already, and lacking
parallelism during the rust build.
So we force .cargo/config to be generated during export (which it is not
already because OBJDIR_PP_FILES are currently dealt with during misc).
That makes Make still run the rust targets early during the compile
tier.
And while here, we extend the if block in recurse.mk that excludes all
the top-level recursion dependencies when running from subdirectories.

Make depend files related to object files are only really useful when
the corresponding build targets are being processed. OTOH, when they are
included too broadly, when the build recurses in the same directory for
different targets (e.g. target-objects, target, host-objects and/or
host), it is possible for one of them to start creating depend files
that the others would end up reading, and those reads might be
incomplete, possibly leading to build failures because Make think it's
malformed.
So, we only include the object files's depend files in when Make is

The hand-written assembly for libffi on aarch64/windows doesn't emit
unwind information. If we ever tried to unwind through these functions,
they'd look like leaf functions, which is decidedly not true and would
cause great pain.
For whatever reason, the original aarch64 libffi functions used
x21/x22/x23/x24 as their (callee-saved) scratch registers. This
convention works on windows as well, but the unwind information on
windows mandates that we start saving callee-saved registers starting
from x19, rather than x21. Rather than rewriting the assembly to use
x19/x20 instead of x21/x22, which would be a large change, we chose
instead to simply save/restore extra registers in the prolog/epilog.
This change does make the stack frame sizes slightly bigger, but an
extra 16 bytes in libffi stack frames should not matter.
The `-TC` change is necessary to make the compiler play nicely with .asm
file suffixes.

When we converted our libffi assembly preprocessing to use
`GENERATED_FILES`, we translated `sed 's%/F[dpa][^ ]*%%g'` to use the Python
regular expression `'F[dpa][^ ]*'`. Note that we missed the leading `/` in
the sed expression; omitting that leading slash causes no end of trouble if
you have particular expressions in your assembly file, such as
"FastFailCode". (I'm a little surprised this hasn't bitten us yet.)
The straightfoward fix is to add the leading slash.
But wait, the rabbit hole goes deeper. The actual bit from libffi's
`msvcc.sh` that this was trying to translate was:
```
echo "$cl -nologo -EP $includes $defines $src > $ppsrc"
"$cl" -nologo -EP $includes $defines $src > $ppsrc || exit $?
output="$(echo $output | sed 's%/F[dpa][^ ]*%%g')"
args="-nologo $safeseh $single $output $ppsrc"
echo "$ml $args"
eval "\"$ml\" $args"
result=$?
```
Note that the sed expression is operating on `$output`, which is a
completely *separate* thing from the output from the result of
preprocessing. In `msvcc.sh`, `$output` is actually some arguments that are
supposed to be passed to the assembler, per the above and the only place in
the script that sets `$output` to a non-trivial value:
```
-o)
outdir="$(dirname $2)"
base="$(basename $2|sed 's/\.[^.]*//g')"
if [ -n "$single" ]; then
output="-Fo$2"
else
output="-Fe$2"
fi
if [ -n "$assembly" ]; then
args="$args $output"
else
args="$args $output -Fd$outdir/$base -Fp$outdir/$base -Fa$outdir/$base"
fi
```
Presumably the sed expression is attempting to remove `-Fd` and friends from
`$args` instead of `$output`, but failing badly at doing so.
In any event, the regex substitution the script is doing is unnecessary and,
with the current code, actively harmful. Let's remove the regular
expression substitution entirely.

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.

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

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.

While this isn't related to the bug, since we're going to touch the
cargo compiler flags, we might as well do this too.
It wasn't previously reliable to pass those flags down because what
cargo uses as target for build scripts and procedural macros is
determined by the rust host, which was not necessarily the same as the
build system host. But as of bug 1523143, they are always the same.

Now that Make invokes cargo without going through an msys shell,
environment variables are going to be preserved properly, and we can now
"safely" pass the compiler-related variables down to cargo on Windows.
This makes rust target builds use the expected compiler and flags,
instead of the cc-rs crate guessing, picking cl.exe, and using the wrong
one, with the build later failing when linking it all together because
one of the objects is not for the right target.
Interestingly, the lmdb code is today built for the wrong target on
aarch64, but somehow, it doesn't break the build on automation,
presumably because the lmdb code is actually dead code, and the linker
eliminates the object as unused, masking the problem.

Double quotes on a command line forces Make to use a msys shell when
invoking the command. Single quotes don't have this effect. This is the
last bit that prevented Make from invoking cargo directly on Windows.

These require some awkward setup to keep things working on
non-cross-compiles on non-Windows, but we'll change that shortly in a
later bug.
