Summary: In case a checker is registered multiple times as an alias, the emitted warnings are uniqued by the report message. However, it is random which checker name is included in the warning. When processing the output of clang-tidy this behavior caused some problems. In this commit the uniquing key contains the checker name too.

When a Record is declared in the global namespace, clang-doc serializes
it as a child of the global namespace, so the global namespace is now
one if its parent namespaces. This namespace was not being included in
the list of namespaces of the Info causing paths to be incorrect and the
index rendered incorrectly.
Affected tests have been fixed.

Bitcode writer was not emitting the corresponding record for the Access attribute of a FunctionInfo. This has been added.
AS_none was being used as the default value for any AcesssSpecifier attribute
(in FunctionInfo and MemberTypeInfo), this has been changed to AS_public
because this is the enum value that evaluates to 0.
The bitcode writer doesn't write values that are 0 so if an attribute
was set to AS_public, this value is not written and after reading the
bitcode it would have the default value which is AS_none. This is why
the default value is now AS_public.

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.

Summary:
If there is no comment, place it at the closing brace of a namespace
definition. Previously it was placed at the next character after the
closing brace.
The new position produces a better location for highlighting in clangd
and does not seem to make matters worse for clang-tidy.

Summary:
Finds non-static member functions that can be made ``static``.
I have run this check (repeatedly) over llvm-project. It made 1708 member functions
``static``. Out of those, I had to exclude 22 via ``NOLINT`` because their address
was taken and stored in a variable of pointer-to-member type (e.g. passed to
llvm::StringSwitch).
It also made 243 member functions ``const``. (This is currently very conservative
to have no false-positives and can hopefully be extended in the future.)

Currently it fails on cases like '\001'.
Note: Since `StringLiteral::outputString` dumps most nonprintable

Instantiate a ClangTidyDiagnosticConsumer also for the plugin case and
let it forward the diagnostics to the external diagnostic engine that is
already in place.
One minor difference to the clang-tidy executable case is that the
compiler checks/diagnostics are referred to with their original name.
For example, for -Wunused-variable the plugin will refer to the check as
"-Wunused-variable" while the clang-tidy executable will refer to that
as "clang-diagnostic- unused-variable". This is because the compiler
diagnostics never reach ClangTidyDiagnosticConsumer.

This patch adjusts `PragmaOpenMPHandler` to set the location of
`tok::annot_pragma_openmp` to the `#pragma` location instead of the
`omp` location so that the former becomes the start location of the
OpenMP AST node. This can be useful when, for example, rewriting a
directive using Clang's Rewrite facility. Most of this patch updates
tests for changes to locations in diagnostics and `-ast-dump` output.
