Summary:
Replaces explicit calls to the constructor in a return with a braced
initializer list. This way the return type is not needlessly duplicated in the
return type and the return statement.
```
Foo bar() {
Baz baz;
return Foo(baz);
}
// transforms to:
Foo bar() {
Baz baz;
return {baz};
}
```

I have made a small fix for readability-delete-null-pointer check so it also checks for class members.
Example of case that it fixes
```
struct A {
void foo() {
if(mp)
delete mp;
}
int *mp;
};

LLVM defines `PTHREAD_LIB` which is used by AddLLVM.cmake and various projects
to correctly link the threading library when needed. Unfortunately
`PTHREAD_LIB` is defined by LLVM's `config-ix.cmake` file which isn't installed
and therefore can't be used when configuring out-of-tree builds. This causes
such builds to fail since `pthread` isn't being correctly linked.
This patch attempts to fix that problem by renaming and exporting
`LLVM_PTHREAD_LIB` as part of`LLVMConfig.cmake`. I renamed `PTHREAD_LIB`
because It seemed likely to cause collisions with downstream users of
`LLVMConfig.cmake`.

clangd is a language server protocol implementation based on clang. It's
supposed to provide editor integration while not suffering from the
confined ABI of libclang.
This implementation is limited to the bare minimum functionality of
doing (whole-document) formatting and rangeFormatting. The JSON parsing
is based on LLVM's YAMLParser but yet most of the code of clangd is
currently dealing with JSON serialization and deserialization.
This was only tested with VS Code so far, mileage with other LSP clients
may vary.

Summary:
Fix no std::function index.
Previously, we don't index all the template specialization declarations of functions and classes (Because we assume that template functions/classes are indexed by their template declarations), but this is not always true in some cases like `std::function` which only has a partial template specialization declaration.

Instead of just using popularity, we also take into account how similar the
path of the current file is to the path of the header.
Our first approach is to get popularity into a reasonably small scale by taking
log2 (which is roughly intuitive to how humans would bucket popularity), and
multiply that with the number of matching prefix path fragments of the included
header with the current file.
Note that currently we do not take special care for unclean paths containing
"../" or "./".
