l10n-merge creates a full merge dir for a while now, let's
simplify the build logic to only read from that directory
during repacks and langpacks.

Instead of doing this:
a) read existing file into memory
b) append new entries
c) sort all entries
d) write unique entries back to file
We now do this:
a) sort new entries
b) loop through existing file entries, one at a time, writing them to a tmp file
c) insert the new entries in between the existing file entries in lexicographic order,
and deduplicating the new entries
d) write any remaining new entries (that are lexicographically after the last
entry in the pre-existing file), again deduplicating the entries
e) move tmp file back to original file location
This avoids reading the entire file into memory which could be potentially
hundreds of MB large.
The changes in FileOperations.* are needed to support these changes, as we now
have two files that we're dealing with - reading from one and writing to the
other. We still use a Mutex (Windows) or exclusive-flock (POSIX) on the file
for the duration of the entire operation, so we should still be robust in the
face of multiple concurrently running clang processes.

The configure sandbox has a list of arguments to handle, and removes
each of them when it resolves the corresponding options through e.g. a
`@depends`. When the configure sandbox is finished, what's supposed to
be left is unknown options.
The mozconfig injections adds elements to that list of arguments to
handle. The problem is that by the time the mozconfig injection happens,
some early options have already been handled by the sandbox and won't be
re-handled. Which means by the end of configure, the arguments are still
there, and the sandbox throws an error because it thinks they are for
unknown options.
Things were actually working before bug 1264527, essentially because we
had an explicit list of mozconfig variables that would be injected, and
that didn't include those early options.
So what we now do is to not actually inject those early options from
mozconfig.

The expanded checks in clang 10 made arm64 builds hit CFG crashes on nsXPTCStubBase vtables on startup.
It's not clear why this doesn't happen on x86 builds. Given our current level of support for arm64, I can't really justify investigating this, although I suspect that fixing the underlying issue would be pretty much bug 1483885.
As a get-unblocked stopgap, `-guard:cf,nochecks` in clang 10 gives the same behavior as `-guard:cf` in clang 9.

Configuration values defined above `mozconfig_options` in `init.configure` are those that can't be configured in `mozconfig`. As far as I can tell there is nothing wrong *in principle* with setting `PYTHON3` in `mozconfig`, so here we just bump `mozconfig_options` above `PYTHON3` configuration.
Side note, diagnosing this failure took a *long* time. The error message that this produced ("unknown option `PYTHON3`") is useless and the underlying algos being extremely mutable, I ended up having to spend a lot of time in the debugger and monitor all the underlying changes to a bunch of mutable data structures to determine where `PYTHON3` was getting lost. A better error message would be good here but I don't know how I would begin adding it.

iOS support for Gecko has not been tested in years and is most probably
out of date. The build system part of it, specifically the checks in
build/autoconf/ios.m4, are not trivial to port to python configure, and
they prevent other things from moving to python configure (because some
of them change value when MOZ_IOS is set).
The code is left alone, although it could probably be stripped off as
well, but I'll leave that as an exercise for someone else.

If we don't do this, configure will happily think the linker kind is
"unknown", which then causes problems downstream.

This patch is adding an option to push a perftest run in the CI.
It's based on :

- push_to_try
- options passed through try_task_config.json

ubsan's generated code trips an optimization corner case in clang 10. This is a short-term workaround. In the best case, llvm.org/pr45835 will land a fix soon, and we can merge that for our clang-10 update and not even land this patch. However, in case we're living in anything other than the best case world, I don't want to block on that happening.
