`os.path.realpath` in Python 3.8 now always uppercases Windows drive letter, while it was just an alias of `os.path.abspath` in Windows. This patch uses `.realpath()` consistently to get `topobjdir` to fix the incompatibility from the behavior change.

Split out jsreftest and jittest files into their own packages, removing them
from the common package.
This speeds up extracting files from the common test archive for
non-jsreftest/jittest suites.
Also, remove some files from the web-platform test archive that are already
present in the common archive.

The original commit message for the order files says "It's OK if these files are slightly out of date", and that's true. However, in the 11 months since then, our builds have undergone major changes that affect large numbers of final symbol names, like switching from Frontend to IR PGO, and enabling the new pass manager. I think at this point a refresh wouldn't hurt.
I generated these files by locally creating a "stage 2.5" PGO build that's both `-fprofile-use` _and_ `-finstrument-functions-after-inlining`, and otherwise following the instructions from bug 1444171. Doing this at the `use` stage rather than the `gen` stage lets us get around the problem of mixing IR and Frontend instrumentation. It also gets us a more accurate picture of the final optimizations.
I haven't exhaustively run this through Talos. I did some spot checks, most were within noise, Speedometer maaybe gets 0.6%. I don't think this is worth hogging the talos machines for a full run, we can get the results after landing.
If for no other reason, this is worth doing to reduce 8000 lines of warning LNK4037 (order file refers to a nonexistent symbol) in build logs down to about 15.

When running e.g. check_symbols with extra flags like when checking
for vpx_codec_dec_init_ver when building against system libvpx, in some
configurations, the test can fail when the library flags (-l) appear
before the source file path.
The reason is that in some configurations, the compiler passes
--as-needed to the linker before both the flags and the object file
path, and the object file path is in the same position as the source
file path was. With --as-needed, -l flags are dropped if the library
wasn't needed for any of the linked code that appears *before* the flag.
So linking with `--as-needed -lfoo foo.o`, is equivalent to linking with
`foo.o` only in practice, while `--as-needed foo.o -lfoo` is equivalent
to `foo.o -lfoo`.

Bug 1568994 moved the URL for the update server to application.ini. Thunderbird
uses a different hostname for the update URL; the URL path is the same.
I've added a set_config('MOZ_APPUPDATE_HOST') to Thunderbird's moz.configure
file which will override the default.

The clang_rt.builtins lib files produced by the 1stage build do not include
functions necessary for 128bit integers. This functionality is required by the
OpenPGP libraries that Thunderbird is using, specifically Botan's bigint module.
When compiler-rt is built with MSVC, these functions are not included
by design.

This matches up to what we were doing before the Python 3 switch. Subprocess.Popen's default encoding doesn't necessarily match up to the system encoding as reported by mozbuild.util.system_encoding, and pre-Python 3.6 the constructor doesn't have `encoding` or `errors` parameters for no apparent reason. In the meantime, do the decoding manually.

Unfortunately, since the new ecdsa library has a different interface and slightly different inner workings compared to the old PyECC library, the changes to support this update are not trivial. Luckily the ecdsa library is extensible enough to allow us to adjust the library's functionality with function parameters rather than monkey-patching, as we were doing with the previous version of the code. All of these interface changes are in addition to the normal rote Python 3 updates. This was tested by running a build with and without this patch and ensuring there were no unexpected diffs.

The V8 code in the new engine uses implicit constructors with wild abandon, and it doesn't seem like a good use of time to try upstreaming a patch to remove them.

One of the recent changes made it so that the test doesn't start on its own unless the URL has "raptor".
I've confirmed that this
- Does not swamp out the profdata file
- Does not regress displaylist-mutate
- Improves the webaudio score

Currently the linux64-clang-9-win-cross toolchain depends on the win64-clang-cl toolchain for a few files. This causes very long lead times when toolchains are rebuilt, because of the un-parallelizable chain of tasks win64-clang-cl -> linux64-clang-9-win-cross -> builds.
As a partial mitigation, this patch adds a single-stage clang-cl build for consumption by the cross toolchain. It's not a very high quality build, but good enough for the purpose it serves, while being faster to build.

This commit removes `test_fix_stack_using_bpsyms.py`. That test can't easily be
modified to work with `fix_stacks.py` because it relies on internal
implementation details of `fix_stack_using_bpsym.py`. The unit testing done in
the `fix-stacks` repo provides test coverage that is as good or better.

The `linux64-clang-9-cross` toolchain was forked from `linux64-clang-9` in https://hg.mozilla.org/integration/autoland/rev/ca923afe3ed4 in order to pick up a patch for Windows compilation.
This is no longer necessary for two reasons:
1. Windows builds stopped depending on that patch in bug 1608460.
2. Even if we still needed that patch, the `linux64-clang-9` toolchain gained all of the Windows patches in bug 1618473.
Therefore the `clang-dist` task can go back to using unmodified `linux64-clang-9`.

This adds the ability to do four-stage PGO builds. This was surprisingly straightforward thanks to PGO being a well-supported scenario in LLVM's cmake.
For reference, the stages are:
stage1: Initial build with gcc
stage2: Instrumented build using stage1
stage3: Train by using the instrumented stage2 to build the clang tree
stage4: Optimize using the stage3 compiler and the profdata created with it

Separating out the mechanical/"boring" changes to make the next patch more clear. This patch adds the ability to build a fourth stage that for now doesn't do anything special.
I changed to using >= to make it more obvious that e.g. "here is what's going to happen for stage 2" -- the off-by-one was too hard on my brain.
