The previous logic would check the value of the `PYTHON3` environment variable, which is not set by the Firefox build system, so this build script tends to just use the `python3` at the tip of the `PATH`, regardless of which value you've configured for it. Instead, it should prefer to read from the `OBJDIR` if one is present.

than a separate loadable library. This means the parts of ICU that can load
such a module are not necessary.

Because jar_maker is not in the libs tier, we also rename the libs-%
targets for l10n repacks to l10n-%, which make it clearer what they are
for.
And because multilocale.txt is both a GeneratedFile and a file that is
generated (and installed) via manual build rules, keeping it in the misc
target actually breaks building in toolkit/locales during l10n repacks,
so move it to libs for now.

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out of date.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.

`ply`, [by design](https://github.com/dabeaz/ply/issues/79), does not produce reproducible table files; hence bug 1633156. (Note that this was *always* true, but only became a problem once we switched to Python 3, which has more unpredictable dict iteration order than Python 2.7, at least prior to [3.7](https://docs.python.org/3/whatsnew/3.7.html#summary-release-highlights).)
In any other circumstance I would consider submitting a patch to `ply` to fix this, but as of the [in-progress version 4.0 of the library](https://github.com/dabeaz/ply/blob/master/CHANGES), it doesn't even emit this cached data any more, and indeed the [latest version of the code](1fac9fed64/ply) doesn't even call `open()` at all except to do logging or to read the text data to be parsed from `stdin`. So if we were going to pin our future on `ply` and upgrade to later versions of the library in the future, we would have to live in a world where `ply` doesn't generate cached table files for us anyway.
Emitting the cached table files so later build steps can consume them is an "optimization", but it's not clear exactly how much actual value that optimization provides overall. Quoth the `CHANGES` file from that repository:
```
PLY no longer writes cached table files. Honestly, the use of
the cached files made more sense when I was developing PLY on
my 200Mhz PC in 2001. It's not as much as an issue now. For small
to medium sized grammars, PLY should be almost instantaneous.
```
In practice, I have found this to be true; namely, `./mach build pre-export export` takes just about as long on my machine after this patch as it did before, and in a try push I performed, there's no noticeable performance regression from applying this patch. In local testing I also found that generating the LALR tables in calls to `yacc()` takes about 0.01s on my machine generally, and we generate these tables a couple dozen times total over the course of the `export` tier now. This isn't *nothing*, but in my opinion it's also not nearly long enough where it would be a concern given how long `export` already takes.
That `CHANGES` file also stresses that if caching this data is important, we have the option of doing so via `pickle`. If and when we decide that re-enabling this optimization is valuable for us, we should take control of this process and perform the generation in such a way that we can guarantee reproducibility.

Linking Rust code against the updatecommon library is not well supported by our build system, but it should be possible. The changes to updatecommon's moz.build will cause updatecommon.lib to be created, which Rust can link against. The build.rs script tells cargo which shared Windows libraries are needed for linking, and where updatecommon.lib can be found. The change to config/recurse.mk enforces the dependency of the update agent on updatecommon, so that we do not attempt to link the agent before updatecommon has been built.

For now this generates just CACHE_IR_OPS and CACHE_IR_SHARED_OPS in CacheIROpsGenerated.h
but the plan is to use this to generate parts of the IR writer and compiler/transpiler
interface. The spewer could also potentially be improved now that each operand has a name
and more precise type.
Generating the IR writer will likely happen incrementally so that will give us
another chance to double check the precise types match what's in the YAML file.

Because most of the recent changes to irregexp were patches I contributed myself, we barely need to change any of the shim code.
The only notable change is the addition of '#define COMPILING_IRREGEXP_FOR_EXTERNAL_EMBEDDER'. This is the solution that Jakob Gruber and I eventually came up with for the question of what to do with awkward V8 code that SM doesn't want. For example, NativeRegExpMacroAssembler::Match (in regexp-macro-assembler.cc) gets down in the muck with the internal details of V8's String implementation. It would be most convenient for SM if that function just didn't exist; we aren't going to use it, and we don't want to have to define a bunch of unused string API gunk in our shim. The answer is to wrap functions we don't need in "#ifndef COMPILING_IRREGEXP_FOR_EXTERNAL_EMBEDDER", which solves our problem and is minimally disruptive upstream.

Dictionary iteration under Python 3 is in an inherently unpredictable order, and while we try to keep DEFINES ordered through the use of OrderedDicts, if at any point we populate DEFINES directly or indirectly while iterating through the contents of a non-ordered dictionary, the order of the DEFINES (and therefore the contents of the output Makefile) will be nondeterministic as well. This patch makes a number of changes to ensure that we only ever populate DEFINES in a deterministic fashion. (Note that in Python 3.7 and later, the built-in dict class actually has deterministic ordering, so these changes are technically only necessary until our minimum Python version becomes 3.7.)
