For x86 Darwin, we have a stack checking feature which re-uses some of this
machinery around stack probing on Windows. Renaming this to be more appropriate
for a generic feature.

Original commit description:
[LLD] Remove global state in lld/COFF
This patch removes globals from the lldCOFF library, by moving globals
into a context class (COFFLinkingContext) and passing it around wherever
it's needed.
See https://lists.llvm.org/pipermail/llvm-dev/2021-June/151184.html for
context about removing globals from LLD.
I also haven't moved the `driver` or `config` variables yet.

PassBuilder.cpp is the slowest file to compile in LLVM.
When trying to test changes to pipelines, it takes a long time to recompile.
This doesn't actually speedup building PassBuilder.cpp itself since most
of the time is spent in other large/duplicated functions caused by
PassRegistry.def.

Follow-up to D109708: Using lib_dirs means this will work with ancient gn binaries.
Change the toolchain definitions to make lib_dirs have the right effect, and
pull out lib_switch of each of the tools while here.
This means we now do pass /LIBPATH: to link.exe, but since we invoke it directly
and not through clang-cl, this doesn't actually require D109624. And since this
is built in to GN, we don't need a config to push the flag to dependents.
This is arguably a bit more idiomatic, and it doesn't require folks to update
their GN binaries. No effective behavior change.

This updates llvm/utils/sysroot.py to include the "DIA SDK" folder in the
sysroot.
It also updates the build to look for the DIA SDK there if a sysroot is set.
This requires moving LLVM_WINSYSROOT to config-ix.cmake.
For the GN build, I chose to pass a qualified path to diaguids in libs instead
of pushing a config with a `/libpath:` flag. The former requires a GN with
https://gn-review.googlesource.com/c/gn/+/12200, the latter requires D109624.
The former is more like the cmake build, arguably a bit simpler, and it's
easier to check for the wrong GN revision and easier to update GN.

The cross-compiled lldb-server targets are added to the lldb deps if
Android cross compilation is enabled.
Differential Revision: https://reviews.llvm.org/D109464
On Linux, LLDB depends on lldb-server at runtime (on Mac, the dependency on
a debug server presumably comes via the system debugserver), so I added it
to deps.

This is enough to get the lit-based tests to pass on macOS.
Doesn't yet add build targets for:
- Any LLDB unit tests
- swig bindings
- various targets not needed by lit tests
LLDB has many dependency cycles, something GN doesn't allow. For
that reason, I've omitted some dependency edges. Hopefully we can
clean up the cycles one day.
LLDB has a public/private header distinction, but mostly ignores it.
Many libraries include private headers from other modules.
Since LLDB is the first target the LLVM/GN build that uses Objective-C++
code, add some machinery to the toolchain file to handle that.
