Summary:
For https://github.com/clangd/clangd/issues/382
This commit adds access specifier information to the hover
contents. For example, the hover information of a class field or
member function will now indicate if the field or member is private,
public, or protected. This can be particularly useful when a developer
is in the implementation file and wants to know if a particular member
definition is public or private.

Summary:
We already skip function bodies from these files while parsing, and drop symbols
found in them. However, traversing their ASTs still takes a substantial amount
of time.
Non-scientific benchmark on my machine:
background-indexing llvm-project (llvm+clang+clang-tools-extra), wall time
before: 7:46
after: 5:13
change: -33%
Indexer.cpp libclang should be updated too, I'm less familiar with that code,
and it's doing tricky things with the ShouldSkipFunctionBody callback, so it
needs to be done separately.

Summary:
Lexing until the token location is past preamble bound could be wrong
in some cases as preprocessor lexer can lex multiple tokens in a single call.

Summary:
FieldDecl::getParent assumes that the FiledDecl::getDeclContext returns a
RecordDecl, this is true for C/C++, but not for ObjCIvarDecl:
The Decls hierarchy is like following
FieldDecl <-- ObjCIvarDecl
DeclContext <-- ObjCContainerDecl <-- ObjCInterfaceDecl
^
|----- TagDecl <-- RecordDecl
calling getParent() on ObjCIvarDecl will:
1. invoke getDeclContext(), which returns a DeclContext*, which points to an ObjCInterfaceDecl;
2. then downcast the "DeclContext" pointer to a RecordDecl*, and we will hit
the "is_a<RecordDecl>" assertion in llvm::cast (undefined behavior
in release build without assertion enabled);

Summary:
The Token objects are relatively expensive and we were spending a lot of
CPU creating them for each trigram emitted. Instead, use a tiny trigram
structure until we're ready to finalize the index.
This improves the new BuildDex benchmark by 20%. This code is hot and on
the critical path in clangd: it runs after a new preamble is built.

Summary:
PCH format is unstable, hence using a preamble built with a different
version of clang (or even worse, a different compiler) might result in
unexpected behaviour.
PCH creation on the other hand is something clangd wouldn't want to perform, as
it doesn't generate any output files.
This patch makes sure clangd drops any PCH related compile commands after
parsing the command line args.

Summary:
Sometimes in templated code Member references are reported as `DependentScopeMemberExpr` because that's what the standard dictates, however in many trivial cases it is easy to resolve the reference to its actual Member.
Take this code:
```
template<typename T>
class A{
int value;
A& operator=(const A& Other){
value = Other.value;
this->value = Other.value;
return *this;
}
};
```
When ran with `clang-tidy file.cpp -checks=readability-identifier-naming --config="{CheckOptions: [{key: readability-identifier-naming.MemberPrefix, value: m_}]}" -fix`
Current behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.value;
this->value = Other.value;
return *this;
}
};
```
As `this->value` and `Other.value` are Dependent they are ignored when creating the fix-its, however this can easily be resolved.
Proposed behaviour:
```
template<typename T>
class A{
int m_value;
A& operator=(const A& Other){
m_value = Other.m_value;
this->m_value = Other.m_value;
return *this;
}
};
```
