Run misc-use-internal-linkage check over clang-tidy code.
Also fixed a couple of other clang-tidy warnings.
Apart from issues in header files, all '.cpp' in
`clang-tools-extra/clang-tidy` must be clang-tidy clear now.
We have multiple different attributes in clang representing device
kernels for specific targets/languages. Refactor them into one attribute
with different spellings to make it more easily scalable for new
languages/targets.

These are identified by misc-include-cleaner. I've filtered out those
that break builds. Also, I'm staying away from llvm-config.h,
config.h, and Compiler.h, which likely cause platform- or
compiler-specific build failures.
If a add_clang_library call doesn't specify building as static or shared
library they are implicitly added to the list static libraries that is
linked in to clang-cpp shared library here.

Because the clang-tools-extra libraries targets were declared after
clang-cpp they by luck never got linked to clang-cpp.
This change is required for clang symbol visibility macros on windows to
work correctly for clang tools since we need to distinguish if a target
being built will be importing or exporting clang symbols from the
clang-cpp DLL.
This patch provides more information to the
`PPCallbacks::InclusionDirective()` hook. We now always pass the
suggested module, regardless of whether it was actually imported or not.
The extra `bool ModuleImported` parameter then denotes whether the
header `#include` will be automatically translated into import the the
module.
The main change is in `clang/lib/Lex/PPDirectives.cpp`, where we take
care to not modify `SuggestedModule` after it's been populated by
`LookupHeaderIncludeOrImport()`. We now exclusively use the `SM`
(`ModuleToImport`) variable instead, which has been equivalent to
`SuggestedModule` until now. This allows us to use the original
non-modified `SuggestedModule` for the callback itself.
(This patch turns out to be necessary for
https://github.com/apple/llvm-project/pull/8011).
The modules build trips over this frequently because there is no textual
include of the tablegen output, but the module includes it.

In Clang notes are typically printed after a corresponding warning, not before.
For example, all notes issued before the first warning are ignored.
Running `clang-tidy --checks=-*,altera-id-dependent-backward-branch a.cpp` on the following code:
```
long get_local_id(int);
void error() {
int ThreadID = get_local_id(0);
for (int i = 0; i < ThreadID; i++) {
}
for (int i = 0; i < ThreadID; i++) {
}
}
```
results in two warnings and a single note in between.

We forgot to apply the change to headers in the previous patch,
due to missing "-header-filter" in the run-clang-tidy invocation.

The needed tweaks are mostly trivial, the one nasty bit is Clang's usage
of OptionalStorage. To keep this working old Optional stays around as
clang::CustomizableOptional, with the default Storage removed.
Optional<File/DirectoryEntryRef> is replaced with a typedef.
I tested this with GCC 7.5, the oldest supported GCC I had around.

This reverts commit 8f0df9f3bbc6d7f3d5cbfd955c5ee4404c53a75d.
The Optional*RefDegradesTo*EntryPtr types want to keep the same size as
the underlying type, which std::optional doesn't guarantee. For use with
llvm::Optional, they define their own storage class, and there is no way
to do that in std::optional.
On top of that, that commit broke builds with older GCCs, where
std::optional was not trivially copyable (static_assert in the clang
sources was failing).
This fixes a problem where __va_list_tag was not correctly imported,
possibly leading to multiple definitions with different types.
This adds __va_list_tag to it's proper scope, so that the ASTImporter
can find it.

This patch changes type of the `File` parameter in `PPCallbacks::InclusionDirective()` from `const FileEntry *` to `Optional<FileEntryRef>`.
With the API change in place, this patch then removes some uses of the deprecated `FileEntry::getName()` (e.g. in `DependencyGraph.cpp` and `ModuleDependencyCollector.cpp`).

We can directly use cast<> instead of separate dyn_cast<> with assertions as cast<> will perform this for us.
Similarly we can replace a if(isa<>)+cast<>/dyn_cast<> with if(dyn_cast<>)
We can only use ASTContext::getTypeInfo for complete types.
This fixes bugzilla issue 50313.
