Fix various tool libraries not to link to clang's .a libraries and dylib
simultaneously. This may cause breakage, in particular through
duplicate command-line option declarations.

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.

Conditionally compile the parts of clang-tidy which depend on the static
analyzer.
Funnily enough, I made the patch to exclude this from the build in 2013,
and it was committed with the comment that the tool should not be fully
excluded, but only the parts of it which depend on the analyzer should
be excluded.

This commit implements that idea.

Summary:
This is part 1 of 3 of a series of changes to improve Objective-C
linting in clang-tidy.
This introduces a new clang-tidy module, `objc`, specifically for
Objective-C / Objective-C++ checks.
The module is currently empty; D39142 adds the first check.

Summary:
A common source of security bugs is code that opens a file descriptors without using the O_CLOEXEC flag. (Without that flag, an opened sensitive file would remain open across a fork+exec to a lower-privileged SELinux domain, leaking that sensitive data.).
Add a new Android module and one checks in clang-tidy.
-- open(), openat(), and open64() should include O_CLOEXEC in their flags argument. [android-file-open-flag]

This check verifies if buffer type and MPI (Message Passing Interface)
datatype pairs match. All MPI datatypes defined by the MPI standard (3.1)
are verified by this check. User defined typedefs, custom MPI datatypes and
null pointer constants are skipped, in the course of verification.
Instructions on how to apply the check can be found at:

This doesn't really do much at the moment. You can load it via libclang
and set the -checks via an extra command line argument as illustrated in
the test case. Support for other options (including headers check) is
currently missing. Also when using this with libclang some checks may
not work with the precompiled preamble in place.
This can be used to easily show clang-tidy warnings in an editor
integration as all that's needed is adding command line flags that are
passed into libclang. Warnings and FixIts are exposed via the existing
CXDiagnostic machinery.
