This required substantially more invasive changes.
We need to handle some of the LLVM `config.h` changes differently from
the old pattern. These aren't always safe on the commandline, and the
Windows ones specifically break Clang. Instead, use conditional defines
in the header itself. This more closely matches how CMake builds see the
definitions. I think this is also just cleaner and we should maybe move
more of the macros out of Bazel.
The config defines for Windows that I've kept in Bazel are the ones that
LLVM's CMake does at the commandline as well. I've also added numerous
ones that CMake uses and we didn't replicate in Bazel.
I also needed a different approach to get `libclang` working well. This,
IMO, improves things on all platforms. Now we build the plugin and
actually wrap it back up with `cc_import`. We have to use a collection
of manually tagged `cc_binary` rules to get the naming to work out the
right way, but this isn't too different from the prior approach. By
directly having a `cc_binary` rule for each platform spelling of
`libclang`, we can actually extract the interface library from it and
correctly depend on it with `cc_import`. I think the result now is much
closer to the intent and to the CMake build for libclang.
Sadly, some tests also needed disabling. This is actually narrower than
what CMake does. The issue isn't indicative of anything serious -- the
test just assumes Unix-style paths.
I also have cleaned up the Windows flags in `.bazelrc` to much more
closely match what CMake does.

Adds basic `--config=clang-cl` to set up the basic options needed, and
then fix a number of issues that surface in Windows builds for me.
With these fixes, `//llvm/...` builds cleanly. One unittest still fails,
but its just due to running out of stack space due to creating a large
number of short-lived stack variables. The test should probably be
decomposed into a set of tests (`LegalizerInfoTest::RuleSets`), but that
seemed like too invasive of a change here and with everything building
cleanly this isn't disrupting me experimenting with Windows builds.
Some parts of `//clang/...` builds, but that will require more work.
This is a temporary fix, better would be to avoid including
llvm/Option/ArgList.h from a Support source file.

After the TargetRegistry.h move, nothing in Support includes headers
from MC. However, files in tablegen use MC headers, so we must add an
entry for them in tblgen srcs.

In attempting to build JAX on Apple Silicon, we discovered an issue with
the bazel configuration in llvm-project-overlay. This patch fixes the
logic, at least when building JAX. More context is included on the

Updates the Bazel configuration for
https://github.com/llvm/llvm-project/commit/ee7d20e84675. We need to
drop the dependency from llvm-tblgen to avoid a dependency cycle:
```
.-> @llvm-project//llvm:llvm-tblgen
| @llvm-project//llvm:tblgen
| @llvm-project//llvm:MC
| @llvm-project//llvm:ProfileData
| @llvm-project//llvm:Core

| @llvm-project//llvm:include/llvm/IR/Attributes.inc

`-- @llvm-project//llvm:llvm-tblgen

It appears this dep was not strictly necessary though. TableGen uses MC
headers but it can get those through Support, which also exports MC
headers due to layering issues.

Users should generally observe no difference as long as they don't use
unintended option forms. Behavior changes:
* `-t=d` is removed. Use `-t d` instead.
* `--demangle=false` and `--demangle=0` cannot be used. Omit the option or use `--no-demangle`. Other flag-style options don't have `--no-` forms.
* `--help-list` is removed. This is a `cl::` specific option.
* llvm-readobj now supports grouped short options as well.
* `--color` is removed. This is generally not useful (only apply to errors/warnings) but was inherited from Support.
Some adjustment to the canonical forms
(usually from GNU readelf; currently llvm-readobj has too many redundant aliases):
* --dyn-syms is canonical. --dyn-symbols is a hidden alias
* --file-header is canonical. --file-headers is a hidden alias
* --histogram is canonical. --elf-hash-histogram is a hidden alias
* --relocs is canonical. --relocations is a hidden alias
* --section-groups is canonical. --elf-section-groups is a hidden alias
OptTable avoids global option collision if we decide to support multiplexing for binary utilities.
* Most one-dash long options are still supported. `-dt, -sd, -st, -sr` are dropped due to their conflict with grouped short options.
* `--section-mapping=false` (D57365) is strange but is kept for now.
* Many `cl::opt` variables were unnecessarily external. I added `static` whenever appropriate.

--no-weak (not in GNU nm) is rarely used anyway.)

This patch introduces a custom rule for expanding the LLVM target
enumeration .def files. This provides a slightly cleaner API for these
rules, but is mostly to permit selects to be used when determining which
LLVM targets to build. Right now the target list is generated at Bazel
configure time, but this will allows us to add functionality to also
control which targets are built based on config settings.
