Instead of using CLANG_ENABLE_STATIC_ANALYZER for use of the
static analyzer in both clang and clang-tidy, add a second
toggle CLANG_TIDY_ENABLE_STATIC_ANALYZER.
This allows enabling the static analyzer in clang-tidy while
disabling it in clang.

The altera struct pack align lint check finds structs that are inefficiently
packed or aligned and recommends packing/aligning of the structs using the
packed and aligned attributes as needed in a warning.
Summary: This adds a new module to enforce standards specific to the llvm-libc project. This change also adds the first check which restricts user from including system libc headers accidentally which can lead to subtle bugs that would be a challenge to detect.

Instead, put all checks in a cmake variable and reference this.
Also, make clangd use the the ClangTidyForceLinker.h header instead
of duplicating the list of modules -- the duplicate copy was missing
the new "darwin" checker added in r373065.

Summary:
Creates a new darwin ClangTidy module and adds the darwin-dispatch-once-nonstatic check that warns about dispatch_once_t variables not in static or global storage. This catches a missing static for local variables in e.g. singleton initialization behavior, and also warns on storing dispatch_once_t values in Objective-C instance variables. C/C++ struct/class instances may potentially live in static/global storage, and are ignored for this check.
The osx.API static analysis checker can find the non-static storage use of dispatch_once_t; I thought it useful to also catch this issue in clang-tidy when possible.
This is a re-land of https://reviews.llvm.org/D67567

Summary:
Now that clang is going to be able to build the Linux kernel again on
x86, and we have gen_compile_commands.py upstream for generating
compile_commands.json, clang-tidy can be used on the Linux kernel
source.
To that end, this commit adds a new clang-tidy module to be used for
checks specific to Linux kernel source. The Linux kernel follows its own
style of C, and it will be useful to separate those checks into their
own module.
This also adds an initial check that makes sure that return values from
the kernel error functions like PTR_ERR and ERR_PTR are checked. It also
makes sure that any functions that directly return values from these
functions are checked.

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.

Extract code that forces linking to the separate header and include it in both plugin and standalone tool.
Try 2: missing header guard and "clang/Config/config.h" are added to the new header.
