This change also prepares for 9119325a to land again.

Adds `mlir_c_runner_utils_hdrs` and `mlir_runner_utils_hdrs` targets which do not depend on `//llvm::Support`.

These can be used by other 'runner.so' targets if they are loaded along with the 'runner_utils.so' without calling `__mlir_execution_engine_init()` twice.

Remove the `DenseMapInfo<std::variant<Ts...>>` variant out from
`llvm/ADT/DenseMapInfo.h` into a separate header
`llvm/ADT/DenseMapInfoVariant.h`

This allows us to remove the `<variant>` include, which is being
transitively and unncessary included in all translation units that
include `llvm/ADT/DenseMap.h`.

There have been similar changes to move out specializations for

    * `APInt.h` fd7e309e and
    * `StringRef.h`/`ArrayRef.h`
      983565a6

to reduce the compilation time. As we are unable to move the
specialization into `<variant>`, we create a separate
`DenseMapInfoVariant.h` header that can be used by anyone who needs this
specialization.

This reduces the total number of preprocessing tokens across the LLVM
source files in lib from (roughly) 1,964,876,961 to 1,936,551,496 - a
reduction of ~1.44%. This should result in a small improvement in
compilation time.

Add ability to be able to group ops together in documentation generation. This
results in section of ops grouped together under one summary & description.
This doesn't do anything special for the groups beyond nesting yet.

Old pattern was missing some cases (e.g. swapping the arguments)
but it also allowed too many cases (e.g. non-empty "absent" or
different arguments for add/mul). This fixes the issues.

Move some of the vmv.v.i handling into the vmv.v.v if. This

The word "attribute" has a specific meaning in LLVM. Avoid using it

It hasn't been written to since https://reviews.llvm.org/D46652, so it
was always empty. I don't have enough context on that diff to know if
the removal of the write to ShowIncludesPretendHeader in that diff was
intentional, but no one's complained about it for five years, so I
assume we're okay to just get rid of it entirely.

`-H` displays a tree of included header files, but that tree is supposed
to omit two categories of header files:
1. Any header files pulled in via `-include`, which the code refers to
   as the "predefines".
2. Any header files whose inclusion was skipped because they'd already
   been included (assuming header guards or `#pragma once`).

`-fshow-skipped-includes` was intended to make `-H` display the second
category of files. It wasn't checking for the first category, however,
so you could end up with only the middle of the `-include` hierarchy
displayed, e.g. the added test would previously output:

```
... /data/users/smeenai/llvm-project/clang/test/Frontend/Inputs/test2.h
. /data/users/smeenai/llvm-project/clang/test/Frontend/Inputs/test.h
```

This diff adds a check to prevent that and correctly omit headers from
`-include` even when `-fshow-skipped-includes` is passed. While I'm
here, add tests for the interaction between `-fshow-skipped-includes`
and `-sys-header-deps` as well.

The ScopedString class has two functions named append. One takes
a va_list, but on some platforms va_list is typedef'd to char*.
That means that this call:

  std::string value;
  Str.append("print this string %s", value.c_str());

The compiler can incorrectly think this is the va_list function,
leading to crashes when calling this. To fix this, change the name
of the va_list function to be vappend to avoid this.
