Summary:
They are now used in ClangdScheduler instead of deferred std::async
computations.
The results of `std::async` are much less effective and do not provide
a good abstraction for similar purposes, i.e. for storing additional callbacks
to clangd async tasks. The actual callback API will follow a bit later.

I tried to silence lit with `| count 0`, which did not work.
Other testcases did not have `-- --` but only `--` in the RUN line.
Maybe this fixes the problem.

This patch removes the targetspecification of a testcase, that broke
for ARM. The underlying problem was fixed which makes it unnecessary to
specify the target architecture (problem was the signedness of `char`).

The bug happened with stream operations, that were not recognized in all cases.
Even there were already existing test for streaming classes, they did not catch this bug.
Adding the isolated example to the existing tests did not trigger the bug.
Therefore i created a new isolated file that did expose the bug indeed.

Summary:
The client can send notifications when it detects watched files have
changed. This patch adds the protocol handling for this type of notification.
For now, the notification will be passed down to the ClangdServer, but it will
not be acted upon. However, this will become useful for the indexer to react
to file changes.
The events could also potentially be used to invalidate other caches
(compilation database, etc).
This change also updates the VSCode extension so that it sends the events.

Summary:
Completion results look much nicer without them.
Informative qualifiers are stored for every method from a base class, even when
calling those methods does not require any qualifiers. For example,
struct Foo { int foo(); };
struct Bar : Foo { };
void test() { Bar(). // Completion item label was 'Foo::foo' before,
// but inserted text was simply 'foo'.
// We now simply show 'foo' in completion item label.
They effectively cluttered the completion list without providing much value.

This is a resubmission of r313270. It broke standalone builds of
compiler-rt because we were not correctly generating the llvm-lit
script in the standalone build directory.
The fixes incorporated here attempt to find llvm/utils/llvm-lit
from the source tree returned by llvm-config. If present, it
will generate llvm-lit into the output directory. Regardless,
the user can specify -DLLVM_EXTERNAL_LIT to point to a specific
lit.py on their file system. This supports the use case of
someone installing lit via a package manager. If it cannot find
a source tree, and -DLLVM_EXTERNAL_LIT is either unspecified or
invalid, then we print a warning that tests will not be able
to run.

This patch simplifies LLVM's lit infrastructure by enforcing an ordering
that a site config is always run before a source-tree config.
A significant amount of the complexity from lit config files arises from
the fact that inside of a source-tree config file, we don't yet know if
the site config has been run. However it is *always* required to run
a site config first, because it passes various variables down through
CMake that the main config depends on. As a result, every config
file has to do a bunch of magic to try to reverse-engineer the location
of the site config file if they detect (heuristically) that the site
config file has not yet been run.
This patch solves the problem by emitting a mapping from source tree
config file to binary tree site config file in llvm-lit.py. Then, during
discovery when we find a config file, we check to see if we have a
target mapping for it, and if so we use that instead.
This mechanism is generic enough that it does not affect external users
of lit. They will just not have a config mapping defined, and everything
will work as normal.
On the other hand, for us it allows us to make many simplifications:
* We are guaranteed that a site config will be executed first
* Inside of a main config, we no longer have to assume that attributes
might not be present and use getattr everywhere.
* We no longer have to pass parameters such as --param llvm_site_config=<path>
on the command line.
* It is future-proof, meaning you don't have to edit llvm-lit.in to add
support for new projects.
* All of the duplicated logic of trying various fallback mechanisms of
finding a site config from the main config are now gone.
One potentially noteworthy thing that was required to implement this
change is that whereas the ninja check targets previously used the first
method to spawn lit, they now use the second. In particular, you can no
longer run lit.py against the source tree while specifying the various
`foo_site_config=<path>` parameters. Instead, you need to run
llvm-lit.py.

This check implements the typebased semantic of `gsl::owner`.
Meaning, that
- only `gsl::owner` is allowed to get `delete`d
- `new` expression must be assigned to `gsl::owner`
- function calls that expect `gsl::owner` as argument, must get either an owner
or a newly created and recognized resource (in the moment only `new`ed memory)
- assignment to `gsl::owner` must be either a resource or another owner
- functions returning an `gsl::owner` are considered as factories, and their result
must be assigned to an `gsl::owner`
- classes that have an `gsl::owner`-member must declare a non-default destructor
There are some problems that occur when typededuction is in place.
For example `auto Var = function_that_returns_owner();` the type of `Var` will not be
an `gsl::owner`. This case is catched, and explicitly noted.
But cases like fully templated functions
```
template <typename T>
void f(T t) { delete t; }
// ...
f(gsl::owner<int*>(new int(42)));
```
Will created false positive (the deletion is problematic), since the type deduction
removes the wrapping `typeAlias`.
