The old code for member method calls did the following:
1) Find the member method calls.
2) Look at their "this" expression.
3) If the "this" is an operator call, check for any of the arguments of the
operator call being invalid.
4) Otherwise (if not an operator call) check for the "this" value being
invalid.
This wasn't right, because the "is invalid" check checks the type and only
considers refcounted things. So if the code looked something like
"foo[i]->call_method()", we would look at the types of "foo" and "i" and
determine that none of those are refcounted types so there is nothing invalid
here (since "foo" is some sort of array type and "i" is an integer). The new
setup just checks whether the "this" value is invalid, which does the type
check on the "this" value itself; in the "foo[i]->call_method()" case on
"foo[i]". We then adjust the exclusions in InvalidArg to consider operator->
on known-live things valid, to allow the thing that we were really trying to
accomplish with the "check for an operator call" bits:
"stackRefPtr->some_method()".
The test coverage being added for the made-up TArray type is meant to catch
things like the geolocation issue that was being hidden by the buggy behavior.
I'm not using nsTArray itself because some header included by nsTArray.h
tries to define operator new/delete bits inline and that triggers warnings that
then cause a clang-plugin test failure, because they're unexpected.

The file is essentially limited to ARM flag tweaks, so we make the
corresponding python configure code ARM-only. In large parts, the
python code sets things up similarly, although in a few places we try to
be smarter about than the current autoconf-based code.
The resulting config.status have been verified to only have
insignificant differences on both arm and aarch64 android builds.

This allows calling a C++ MOZ_CAN_RUN_SCRIPT method that takes a callback argument.

Updating clang indicates that 32-bit compilation is substantially longer
than 64-bit compilation, perhaps due to swapping. The compilation
process is hitting the timeout limit shortly before the compilation
process completes (~3681/3695 tasks according to ninja).
We could tweak our clang build process to accommodate this job. But we
don't support building on 32-bit Windows anymore, and we don't produce a
32-bit Windows clang either. So we shouldn't support a 32-bit Windows
clang-tidy job either. Let's get rid of it.

These toolchain tasks are the last ones using the historical
download-tools script from build/unix/build-gcc, which invokes gpg to
validate the downloaded tarballs. The consequence is that gpg-agent is
spawned and stays running, preventing a cleanup script from doing its
job, making the tasks fail.
Fetches are the new way to download sources, and can also do gpg
validation without those caveats.
The download-tools.sh script can then be removed as it's not used
anymore.

Artifact mozconfigs are not necessarily up-to-date wrt changes to the
nightly mozconfigs, and all in all, shouldn't be much different from
them.
It's just better to use the nightly mozconfigs (or beta on beta, etc.)
and make the mozconfigs themselves handle the few things that need to be
different when the USE_ARTIFACT environment is set (which is now
consistently set by taskcluster)
This does have the side effect of turning builds that actually don't
support artifact builds red when using --artifact on try, instead of
having them silently not be artifact builds as currently happens.

The artifact builds that are automatically derived using the artifact
template set the USE_ARTIFACT environment variable from taskcluster.
After the previous change, --artifact builds from try syntax do that
too.
That leaves us with only the artifact-build build not doing it, so for
consistency, do it there. That makes it not necessary to set
USE_ARTIFACT from mozconfig.artifact.automation anymore.
