The test didn't test anything actually -- it used "[]" as annotation which should be
"[[]]".
This patch also fixes a bug in XRef where we may return duplicated refs.

Summary:
This significantly improves performance of background indexing.
We do not collect references and declarations inside the processed
files, so this does not affect the final indexing results.
The idea is borrowed from libclang, which has a similar optimization in
its indexing functionality.
Measurements show a nice decrease in indexing time, up to ~40% for
building the whole index. These are not proper benchmarks, so one should
not rely on these results too much.
1. Rebuilding the whole index for LLVM:
- Before. Total time: 14m58s.
./bin/clangd -pch-storage=memory < ./clangd.input 23917.67s user 515.86s system 2718% cpu 14:58.68 total
- After. Total time: 8m41s.
./bin/clangd -pch-storage=memory < ./clangd.input 13627.29s user 288.10s system 2672% cpu 8:40.67 total
2. Rebuilding index after removing shards matching '*clangd*' (case-insensitively):
- Before. Total time: 30s.
./bin/clangd -pch-storage=memory < ./clangd.input 130.94s user 6.82s system 452% cpu 30.423 total
- After. Total time: 26s.
./bin/clangd -pch-storage=memory < ./clangd.input 80.51s user 5.40s system 333% cpu 25.777 total

Summary:
Adds semantic highlighting for tokens that are a macro argument.
Example:
```
D_V(SomeVar);
```
The "SomeVar" inside the macro is highlighted as a variable now.
Tokens that are in a macro body expansion are ignored in this patch for three reasons.
* The spelling loc is inside the macro "definition" meaning it would highlight inside the macro definition (could probably easily be fixed by using getExpansionLoc instead of getSpellingLoc?)
* If wanting to highlight the macro definition this could create duplicate tokens. And if the tokens are of different types there would be conflicts (tokens in the same range but with different types). Say a macro defines some name and both a variable declaration and a function use this, there would be two tokens in the macro definition but one with Kind "Variable" and the other with Kind "Function".
* Thirdly, macro body expansions could come from a file that is not the main file (easily fixed, just check that the Loc is in the main file and not even a problem if we wanted to highlight the actual macro "invocation")

it as a child of the global namespace, so the global namespace is now

Summary:
This patch introduces a new `analyzer-config` configuration:
`-analyzer-config silence-checkers`
which could be used to silence the given checkers.
It accepts a semicolon separated list, packed into quotation marks, e.g:
`-analyzer-config silence-checkers="core.DivideZero;core.NullDereference"`
It could be used to "disable" core checkers, so they model the analysis as
before, just if some of them are too noisy it prevents to emit reports.
This patch also adds support for that new option to the scan-build.
Passing the option `-disable-checker core.DivideZero` to the scan-build
will be transferred to `-analyzer-config silence-checkers=core.DivideZero`.

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:
clangd supports a -j option to limit the amount of threads to use for parsing
TUs. However, when using -background-index (the default in later versions of
clangd), the parallelism used by clangd defaults to the hardware_parallelisn,
i.e. number of physical cores.
On shared hardware environments, with large projects, this can significantly
affect performance with no way to tune it down.
This change makes the -j parameter apply equally to parsing and background
index. It's not perfect, because the total number of threads is 2x the -j value,
which may still be unexpected. But at least this change allows users to prevent
clangd using all CPU cores.

Summary:
Clang generates function bodies and puts them in the AST for default methods if it is defaulted outside the class definition.
`
struct A {
A &operator=(A &&O);
};
A &A::operator=(A &&O) = default;
`
This will generate a function body for the `A &A::operator=(A &&O)` and put it in the AST. This body should not be visited if implicit code is not visited as it is implicit.
This was causing SemanticHighlighting in clangd to generate duplicate tokens and putting them in weird places.
