It was added in 2014 in 732e0aa9fb with one use in Scalarizer.cpp.
That one use was then removed when porting to the new pass manager in
2018 in b6f76002d9.
While the RFC and the desire to get off of static initializers for
cl::opt all still stand, this code is now dead, and I think we should
delete this code until someone is ready to do the migration.
There were many clients of CommandLine.h that were it transitively
through LLVMContext.h, so I cleaned that up in 4c1a1d3cf9.

Summary:
By additional regex match, grouping of main include can be enabled in files that are not normally considered as a C/C++ source code.
For example, this might be useful in templated code, where template implementations are being held in *Impl.hpp files.
On the occassion, 'assume-filename' option description was reworded as it was misleading. It has nothing to do with `style=file` option and it does not influence sourced style filename.

This patch is motivated by (and factored out from)
https://reviews.llvm.org/D66121 which is a debug info bugfix. Starting
with DWARF 5 all Objective-C methods are nested inside their
containing type, and that patch implements this for synthesized
Objective-C properties.
1. SemaObjCProperty populates a list of synthesized accessors that may
need to inserted into an ObjCImplDecl.
2. SemaDeclObjC::ActOnEnd inserts forward-declarations for all
accessors for which no override was provided into their
ObjCImplDecl. This patch does *not* synthesize AST function
*bodies*. Moving that code from the static analyzer into Sema may
be a good idea though.
3. Places that expect all methods to have bodies have been updated.
I did not update the static analyzer's inliner for synthesized
properties to point back to the property declaration (see
test/Analysis/Inputs/expected-plists/nullability-notes.m.plist), which
I believed to be more bug than a feature.

Summary:
D23319 introduced python3 compatibility to clang-format.py, this is however not reflected by the documentation in the comments at the beginning of the file, which show how to use the script with python2 in .vimrc. While the actual mapping a user might want to use may well differ from my suggestion, I think it's nice to show the python2 and python3 version, such that a user can pick from the suggestions instead of googeling the python3 replacement for `:pyf` which they might not be familiar with.

Previously, given a CompilationDatabase with two commands for the same
source file we would report that file twice with the union of the
dependencies for each command both times.
This was due to the way `ClangTool` runs actions given an input source
file (see the comment in `DependencyScanningTool.cpp`). This commit adds
a `SingleCommandCompilationDatabase` that is created with each
`CompileCommand` in the original CDB, which is then used for each
`ClangTool` invocation. This gives us a single run of
`DependencyScanningAction` per `CompileCommand`.
I looked at using `AllTUsToolExecutor` which is a parallel tool
executor, but I'm not sure it's suitable for `clang-scan-deps` as it
does a lot more sharing of state than `AllTUsToolExecutor` expects.

Summary:
The variable LLVM_NO_DEAD_STRIP is set in LLVM cmake files when building executables that might make use of plugins .The name of the variable does not convey the actual intended usage (i.e. for use with tools that have plugins), just what the eventual effect of setting in on some (i.e. not garbage collecting unused symbols).
This patch renames it to LLVM_SUPPORT_PLUGINS to convey the intended usage, which will allow subsequent patches to add behavior to support that in different ways without confusion about whether it will do on, for example, non-gnu platforms.

Allow finding installed llvm-objcopy in PATH if it's not present
in the directory containing clang-offload-bundler. This is the case
if clang is being built stand-alone, and llvm-objcopy is already

This is consistent with how e.g. llvm-symbolizer is found in LLVM.
However, most of similar searches in LLVM and Clang are performed
without special-casing the program directory.

On seeing a quote on twitter by @invalidop
> If it's not formatted with clang-format it's a build error.
This made me want to change the way I use clang-format into a tool that could optionally show me where my source code violates clang-format syle.
When I'm making a change to clang-format itself, one thing I like to do to test the change is to ensure I didn't cause a huge wave of changes, what I want to do is simply run this on a known formatted directory and see if any new differences arrive in a manner I'm used to.
This started me thinking that we should allow build systems to run clang-format on a whole tree and emit compiler style warnings about files that fail clang-format in a form that would make them as a warning in most build systems and because those build systems range in their construction I don't think its unreasonable to NOT expect them to have to do the directory searching or parsing the output replacements themselves, but simply transform that into an error code when there are changes required.
I am starting this by suggesing adding a -n or -dry-run command line argument which would emit a warning/error of the form
Support for various common compiler command line argumuments like '-Werror' and '-ferror-limit' could make this very flexible to be integrated into build systems and CI systems.
```

This patch removes the remaining part of the OpenMP offload linker scripts which was used for inserting device binaries into the output linked binary. Device binaries are now inserted into the host binary with a help of the wrapper bit-code file which contains device binaries as data. Wrapper bit-code file is dynamically created by the clang driver with a help of new tool clang-offload-wrapper which takes device binaries as input and produces bit-code file with required contents. Wrapper bit-code is then compiled to an object and resulting object is appended to the host linking by the clang driver.
This is the second part of the patch for eliminating OpenMP linker script (please see https://reviews.llvm.org/D64943).
