`TypeSet::unknownObject()` checks if `TYPE_FLAG_UNKNOWN` or `TYPE_FLAG_ANYOBJECT`
is set, but since the previous call to `TypeSet::unknown()` already filters
`TYPE_FLAG_UNKNOWN`, we only need to care about `TYPE_FLAG_ANYOBJECT` here. When
we additionally set `TYPE_FLAG_ANYOBJECT` for the `baseObjectCount() != 0` case,
we can conflate the whole operation into a single bit-and instruction.
This will also simplify part 3.

This gets rid for the need of a number of local packages (mostly related
to Gtk+3). One exception is that we now need a 32-bits version of the
xz-utils package, some -dev package depends on it, and that dependency
can't be fulfilled in the 32-bits image because we already have the
64-bits backport installed, which conflicts with it (we need both
32-bits and 64-bits package to be at the same version when installed).
The system binutils fails to link clang-7 for some reason, so we now use
our toolchain binutils instead, like we already do for newer versions of
clang.
The debian-packages docker image now needs an explicit installation of
git, because it's not pulled in via the recommends of some other
package.
For some reason, snapshot.debian.org doesn't contain the jessie-backports
archive at the same location as others, and only has a few snapshots of

These elements handle focus on their own. They're right now not
having outlines because they specify background-color, which disables
theming, but that is about to change.

When building in some configurations of rustc (e.g. i386 without SSE), building Firefox fails with, among other things:
```
error[E0428]: the name `U1024` is defined multiple times
```
This comes from the typenum library. The issue was fixed in 14a3322d10, so all it takes is an upgrade of the crate.

This seems to come from bug 618907, which seems to be a hack-around code
that went away in bug 1595435.
If we open a window on mousedown such as it gains focus before this code
runs, we just steal the focus from it, which is undesired.
Also remove the test for bug 799299. It doesn't work anyways if the
browser is remote (this test only runs on non-e10s mode), and this
unifies the behavior with e10s and with content (see attached test-case,
which doesn't change behavior with and without my patch).

Events are timestamped to millisecond precision only, so we need to trim
down our clock source a bit.
This also renames the previously used function to make it more clear
(even though an "instant" doesn't really have a unit, so our analogy is
breaking down)

Having all logic for an IC site in WarpBuilder::buildIC will make it easier to
make future changes (like bailing out for cold Baseline ICs). It also enforces
all ICs are handled consistently and it de-duplicates code for JSOps that use
the same CacheKind.
This patch also adds transpiler support for some JSOps (In, InstanceOf, etc) and
we now assert the transpiler (buildIC) is called with the right number of inputs
(based on the CacheKind).

While we're going to rebuild all the Debian-based docker images, we
might as well add one corrective thing that is going to be required
later on, and would require another rebuild, while doing it now would
skip that.
On Debian 10, the python3 distutils module is in a separate package,
python3-distutils, which didn't exist in previous Debian releases,
because back then the distutils module was part of the python3 package.
Fortunately, the python3-distutils-extra package existed on all the
Debian versions we use and depends on the distutils module, so it is a
convenient way to have the python3-distutils package pulled in without
altering the list of packages to install based on the Debian version.

Combined with the upcoming upgrade of the build environment to Debian 8,
which is also going to upgrade the Gtk+3 requirement to 3.14, of the
major Linux distros Firefox currently supports running on, this removes
runtime support for:
- Fedora 20 and earlier (EOLed in 2015),
- OpenSUSE 13.1 and earlier (EOLed in 2016),
- Debian 7 (EOLed in 2018),
- Ubuntu 14.04 (EOLed in 2019).
Some of them might actually be supported in practice because the Gtk+3
requirement might be more relaxed than 3.14, but figuring that out is not
worth the effort.

We currently check that the binaries we ship are not using symbol
versions of system libraries that would not be available on some older
systems. In some cases, however, we may get dependencies on newer symbol
versions in the form of weak symbols, that are checked for at runtime.
This happens with __cxa_thread_atexit_impl when building against a glibc
newer than 2.18, and the supporting code in Rust libstd actually checks
at runtime whether the weak symbol is resolved before using it.
