- Add NumberFormatterSkeleton as a helper class to construct a number formatter
skeleton. When the "Intl.NumberFormat Unified API" proposal gets implemented
a more feature-rich class may be necessary.
- In addition to a UNumberFormatter instance, NumberFormatObject now also
stores a UFormattedNumber instance. This avoids a performance regression
compared to creating a new UFormattedNumber object each time a number gets
formatted. (In micro-benchmarks 20% regressions were seen, with a cached
UFormattedNumber the same micro-benchmarks even improved by ~33%.)
- Add accessors for reserved slot values to NumberFormatObject to improve

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.

The condition that enabled ELOG to do something has been broken since
bug 279212 landed two years ago, because MAKEFLAGS doesn't contain the
dash for flags, so looking for "-s" never did anything.
Bug 1560527 changed the condition to !BUILD_VERBOSE_LOG, which as of the
previous commit, does work. This would restore the old behavior, at the
expense of build time, since it involves wrapping in a shell script,
which is not necessarily desirable (and hasn't been done for two years
now)

Windows 1-tier PGO builds only partially clobber between the
profile-generate and profile-use stages, so that exports/installed files
don't have to be reprocessed. Unfortunately we can't skip the install
manifests in 3-tier PGO because the profile-generate build happens on a
different machine, so we have to differentiate between 1-tier and 3-tier
PGO builds. A new variable, MOZ_1TIER_PGO, is used for this purpose.
Eventually this logic can be cleaned up in bug 1557788 once all PGO
builds use the 3-tier model.

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.

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.
