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.

**Problem:**
Clang-tidy check misc-unused-parameters comments out parameter name omitting following characters (e.g. square brackets) what results in its complete removal. Compilation errors might occur after clang-tidy fix as well.
**Patch description:**
Changed removal range. The range should end after parameter name, not after whole parameter declarator (which might be followed by e.g. square brackets).

This patch is still breaking several multi-stage compiler-rt bots.
I already know what the fix is, but I want to get the bots green
for now and then try re-applying in the morning.

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`.

This check is relatively simple, and is often being used
as an example. I'm aware of at least two cases, when
simply copying the FunctionASTVisitor class to a new
check resulted in a rather unobvious segfault. Having it
in anonymous namespace prevents such a problem.
No functionality change, so i opted to avoid phabricator,
especially since clang-tidy reviews are seriously jammed.

Summary:
The language server protocol specified 2 headers (Content-Length and Content-Type), but does not specify their sequence. It specifies that an empty line ends
headers. Clangd has been updated to handle arbitrary sequences of headers, extracting only the content length.

Support running the extra clang tool tests when the static analyzer
is disabled. Disable the relevant clang-tidy tests and one include-fixer
test that require it to work.
Previously, the tests were disabled entirely with
CLANG_ENABLE_STATIC_ANALYZER being false. Now, the tests are being
enabled and the relevant tests are excluded and marked unsupported
appropriately.
In order to disable clang-tidy tests, the whole test directory is added
to the exclude lists, to avoid having to explicitly add 'REQUIRES' line
to every single test. If the other solution is preferable, I can update
the patch.
The yamldb_plugin include-fixer test is also updated to be disabled
without static analyzer. It fails in that case because clang is not
outputting a replacement suggestion -- but I don't know the exact
reason why it does not do that.
