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.

This needs a few adjustments to the autobinscope script because running
binscope currently creates an HTML file in the binscope directory, and
when multiple binscopes run at the same time (which happens during the
build with the changes to run it on all executables and libraries), all
but one fail to open the HTML file for write access.
So add a flag to create that file in a temporary directory.
While here, remove log_file_path, which hasn't been used since
bug 1448306.

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.)

- Remove the separate option() for MT, because it dates back from when
we needed `MT` not being an absolute path, but that hasn't been true
since bug 1290040.
- Extend what was done in bug 1617794 to MT, although the long term move
is to not rely on MT at all.
- Patch leftovers from bug 1613799.

Windows programs run via Wine don't like Unix absolute paths (they look
like command line arguments), so we need to use relative paths.
Mingw already run fxc2 via wine, but for some reason it doesn't care
about the Unix absolute paths. genshaders does need some adjustements to
run properly with the real fxc.
Now, on actual Windows, because the temporary directory where
tempfile.NamedTemporaryFile creates files by default is not necessarily
on the same drive as where the command runs from, a relative path can't
be constructed. So we also force the temporary file to be created in the
current (obj) directory.
There is no similar concern for other files because we only go from
objdir to srcdir, and the build system already doesn't support both
being on a separate drive.
While here, flush stdout when the genshared script writes to it, so that
the messages are printed out immediately rather than randomly, later,
after output from subprocesses.

GENERATED_FILES now defaults to python3 unless py2=True is specified as
an argument. All existing GENERATED_FILES scripts and GeneratedFile
templates have the py2=True attribute added, so this patch should
effectively be a no-op.
Going forward, individual scripts can be converted to python3 and their
corresponding py2=True attribute can be deleted. In effect, this patch
will be backed out in pieces until all scripts run in python3, at which
point the py2 attribute itself can be removed.

This change is a little gross, because we don't totally control where
the statically initialized instances of `RWLock` live, due to its uses
in third-party libraries.

- -NOLOGO is used to hide the banner that MSVC displays by default. It's
a no-op with clang-cl, no need to keep it now that we don't support
MSVC.
- -utf-8 is only passed when the compiler is not GCC-ish and not
clang-cl, which used to mean MSVC, but now means no compiler.

`lucetc` by default will invoke `ld` directly, which is usually not what
we want, particularly when cross-compiling. Instead, let's invoke the
compiler, which will do the hard work of determining the correct linker
to use, and we'll also explicitly specify `LDFLAGS`, since the default
`LDFLAGS` from `lucetc` assume you're invoking the linker directly.
