`-view-edge-bundles`. NFC. (#106661)
With `-view-edge-bundles`, before the change, the dot file output is
kinda like
```dot
digraph {
"%bb.0" [ shape=box ]
0 -> "%bb.0"
"%bb.0" -> 1
"%bb.0" -> "%bb.1" [ color=lightgray ]
"%bb.0" -> "%bb.6" [ color=lightgray ]
"%bb.1" [ shape=box ]
1 -> "%bb.1"
"%bb.1" -> 1
"%bb.1" -> "%bb.2" [ color=lightgray ]
"%bb.1" -> "%bb.6" [ color=lightgray ]
"%bb.2" [ shape=box ]
1 -> "%bb.2"
"%bb.2" -> 1
"%bb.2" -> "%bb.3" [ color=lightgray ]
"%bb.3" [ shape=box ]
1 -> "%bb.3"
"%bb.3" -> 2
"%bb.3" -> "%bb.4" [ color=lightgray ]
"%bb.4" [ shape=box ]
2 -> "%bb.4"
"%bb.4" -> 2
"%bb.4" -> "%bb.4" [ color=lightgray ]
"%bb.4" -> "%bb.5" [ color=lightgray ]
"%bb.5" [ shape=box ]
2 -> "%bb.5"
"%bb.5" -> 1
"%bb.5" -> "%bb.6" [ color=lightgray ]
"%bb.5" -> "%bb.3" [ color=lightgray ]
"%bb.6" [ shape=box ]
1 -> "%bb.6"
"%bb.6" -> 3
}
```
However, the graph output by graphviz is
The node name corresponding to the MBB is incorrect.
After the change, the node name is consistent with MBB's name.

Looking at the Doxygen-generated documentation for the llvm namespace
currently shows all sorts of random comments from different parts of the
codebase. These are mostly caused by:
- File doc comments that aren't marked with \file, so they're attached to
the next declaration, which is usually "namespace llvm {".
- Class doc comments placed before the namespace rather than before the
class.
- Code comments before the namespace that (in my opinion) shouldn't be
extracted by doxygen at all.
This commit fixes these comments. The generated doxygen documentation now
has proper docs for several classes and files, and the docs for the llvm
and llvm::detail namespaces are now empty.

EdgeBundles.h has no use for it.

This file lists every pass in LLVM, and is included by Pass.h, which is
very popular. Every time we add, remove, or rename a pass in LLVM, it
caused lots of recompilation.
I found this fact by looking at this table, which is sorted by the
number of times a file was changed over the last 100,000 git commits
multiplied by the number of object files that depend on it in the
current checkout:
recompiles touches affected_files header
342380 95 3604 llvm/include/llvm/ADT/STLExtras.h
314730 234 1345 llvm/include/llvm/InitializePasses.h

137647 59 2333 llvm/include/llvm/Support/Error.h
131619 73 1803 llvm/include/llvm/Support/FileSystem.h
Before this change, touching InitializePasses.h would cause 1345 files
to recompile. After this change, touching it only causes 550 compiles in
an incremental rebuild.

This patch applies clang-tidy's bugprone-argument-comment tool
to LLVM, clang and lld source trees. Here is how I created this
patch:
$ git clone https://github.com/llvm/llvm-project.git
$ cd llvm-project
$ mkdir build
$ cd build
$ cmake -GNinja -DCMAKE_BUILD_TYPE=Debug \
-DLLVM_ENABLE_PROJECTS='clang;lld;clang-tools-extra' \
-DCMAKE_EXPORT_COMPILE_COMMANDS=On -DLLVM_ENABLE_LLD=On \
-DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ ../llvm
$ ninja
$ parallel clang-tidy -checks='-*,bugprone-argument-comment' \
-config='{CheckOptions: [{key: StrictMode, value: 1}]}' -fix \
::: ../llvm/lib/**/*.{cpp,h} ../clang/lib/**/*.{cpp,h} ../lld/**/*.{cpp,h}

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

As part of the unification of the debug format and the MIR format, print
MBB references as '%bb.5'.
The MIR printer prints the IR name of a MBB only for block definitions.

the upper limit on the block IDs since basic blocks might get removed (simplified away) after being initially numbered. Plus the test case, in which SelectionDAGBuilder::visitBr() calls llvm::MachineFunction::removeFromMBBNumbering(), which introduces the hole in numbering leading to an assert in llc (prior to the fix).

It is common for large live ranges to have few basic blocks with register uses
and many live-through blocks without any uses. This approach grows the Hopfield
network incrementally around the use blocks, completely avoiding checking
interference for some through blocks.

The analysis will be needed by both the greedy register allocator and the
X86FloatingPoint pass. It only needs to be computed once when the CFG doesn't
change.
This pass is very fast, usually showing up as 0.0% wall time.
