Clang 8 seems to generate destructor decls from different source
locations which breaks an assertion in the code. This patch updates the
code to remove the assertion and more robustly handle the new
declarations.

It turns out, we don't need to `mk_add_options export` the variables
from the in-tree mozconfigs. If anything, that causes problems when
trying to simplify the mozconfigs, because it makes the variables
exported from .mozconfig.mk, overriding what configure may change and
store in autoconf.mk.
All the variables are handled by configure in a way that makes them
available in autoconf.mk, so there's no loss there, and with the
python/shell-based mozconfig loader, it turns out we don't need to go
through extra normalization via cmd.
autospider.py, being its own pseudo-mozconfig parser, still does need
it, though, but it was hooking into it already, so just inline that.

Previously, we hardcoded HostX64 because configure would autodetect a
x86 host on x64 machines, but the x86 MSVC compiler wouldn't be
suitable.
While the x86 MSVC compiler might still not be suitable, now that
configure detects x64 hosts properly, when the configure host is
detected as x86, we can't even execute the x64 compiler, so we can at
least try with the x86 one correctly.

The combination of bug 1515579 and bug 1520394 made things harder for
old-configure, because it doesn't necessarily have a complete view of
the search PATH that has been used. This doesn't actually cause problems
on non-Windows builds because things work out fine, but on Windows,
some of the executions of clang-cl in old-configure insist on being able
to find a MSVC install. That, again, doesn't currently cause problems in
general on local builds because clang-cl finds it through the registry
(presumably), and on automation, because it's in the `mk_add_options
export`'ed PATH, but the latter is due to change.

Bug 1520394 changed things such that the configure sandbox is using a
copy of os.environ. So when mozconfig injects environment changes, they
only affect the sandbox. Which means when the which module uses
os.environ to get PATH, it gets the original unmodified environment.
So instead of relying on the which module getting PATH itself, we feed
it with it. It's worth noting that the which module adds `.` on Windows,
but we don't copy this behavior, because in the context of configure,
it's actually not important (`.` would be the topobjdir).

And use it as an alternative to vswhere, instead of the current late

config.guess doesn't actually figure out the real host system on
Windows. All it does is end up finding the CPU for which the msys used
for the shell is built for. Which has the unfortunate effect that if you
build on a 64-bits host, configure pretends the host is 32-bits.
So instead, rely on some environment variables that should be set
mostly everywhere, and derive the corresponding triplet.
This has two effects:
- configure now knows that the host is 64-bits when it is.
- consequently, configure will build a 64-bits Firefox on 64-bits hosts
by default (since by default, the target is derived from the host), and
that's actually a desired side effect.

- We assume the output from config.guess is sufficiently normalized for

- If we partially derive the target from the host (with only the cpu
given for --target), we assume the derived value doesn't need
canonicalization.

In fact, "simply" use whatever python configure does to find a shell to
execute config.guess and config.sub, and get both the mozconfig content
and the real, canonicalized target alias. This has the side effect of
making builds with --target=$cpu use a complete obj-$cpu-$os default
objdir instead of obj-$cpu. This will also allow to change the
host-guessing logic without having to duplicate code.

Because old-configure is only refreshed when, essentially,
old-configure.in changes, hardcoded (absolute) paths don't necessarily
match the build environment of the current build.
So instead, use an environment variable that we pass from python
configure when invoking old-configure.
Also do dummy changes to old-configure.in so that old-configure is
refreshed at least once to get the environment-based value.

Rust ships with some natvis files that enable nicer display of Rust standard
library types in Microsoft's debuggers. rustc will add the right linker
options to include them when it invokes the linker but since we don't link
libxul with rustc we need to explicitly pass them to the linker ourselves.
This change locates all natvis files in the Rust sysroot and adds them
to the libxul link line.
