Haojian Wu 7f51b5dc32 [clangd] Using symbol name to map includes for STL symbols.
Summary:
Using suffix path mapping relies on the STL implementations, and it is
not portable. This patch is using symbol name mapping, which should
work with different STL implementations, fix clangd/clangd#9.

To generate the symbol mapping, we parse the cppreference symbol index
page to build a lookup table.

The mapping is not completed, a few TODOs:
  - support symbols from different headers (e.g. std::move)
  - support STL macros
  - support symbols from std's sub-namespaces (e.g. chrono)

Kadir Cetinkaya d9c174648e [clangd] Store explicit template specializations in index for code navigation purposes
Summary:
This introduces ~4k new symbols, and ~10k refs for LLVM. We need that
information for providing better code navigation support:
- When references for a class template is requested, we should return these specializations as well.
- When children of a specialization is requested, we should be able to query for those symbols(instead of just class template)

Number of symbols: 378574 -> 382784
Number of refs: 5098857 -> 5110689

Summary:
Addressing: PR25010 - https://bugs.llvm.org/show_bug.cgi?id=25010

Code like:

```
    if(true) var++;
    else  {
        var--;
    }
```

is reformatted to be

```
  if (true)
    var++;
  else {
    var--;
  }
```

Even when `AllowShortIfStatementsOnASingleLine` is true

The following revision comes from a +1'd suggestion in the PR to support AllowShortIfElseStatementsOnASingleLine

This suppresses the clause prevents the merging of the if when there is a compound else

Kadir Cetinkaya 65944ab50d [clangd] Adjust compile commands to be applicable for tooling
Summary:
As can be seen in https://github.com/llvm-mirror/clang/blob/master/lib/Tooling/Tooling.cpp#L385
clang tool invocations adjust commands normally like this. In clangd we have
different code paths for invoking a frontend action(preamble builds, ast builds,
background index, clangd-indexer) they all work on the same GlobalCompilationDatabase
abstraction, but later on are subject to different modifications.

This patch makes sure all of the clangd actions make use of the same compile
commands before invocation.

Enables background-index to work on chromium codebase(since they had dependency
file output in their compile commands).

Shoaib Meenai 5be71faf4b [build] Rename clang-headers to clang-resource-headers
Summary:
The current install-clang-headers target installs clang's resource
directory headers. This is different from the install-llvm-headers
target, which installs LLVM's API headers. We want to introduce the
corresponding target to clang, and the natural name for that new target
would be install-clang-headers. Rename the existing target to
install-clang-resource-headers to free up the install-clang-headers name
for the new target, following the discussion on cfe-dev [1].

I didn't find any bots on zorg referencing install-clang-headers. I'll
send out another PSA to cfe-dev to accompany this rename.

Paul Hoad 68f5e5456f [clang-tidy] add OverrideMacro to modernize-use-override check
Summary:
The usefulness of **modernize-use-override** can be reduced if you have to live in an environment where you support multiple compilers, some of which sadly are not yet fully C++11 compliant

some codebases have to use override as a macro OVERRIDE e.g.

```
// GCC 4.7 supports explicit virtual overrides when C++11 support is enabled.
```

This allows code to be compiled with C++11 compliant compilers and get warnings and errors that clang, MSVC,gcc can give, while still allowing other legacy pre C++11 compilers to compile the code. This can be an important step towards modernizing C++ code whilst living in a legacy codebase.

When it comes to clang tidy, the use of the **modernize-use-override** is one of the most useful checks, but the messages reported are inaccurate for that codebase if the standard approach is to use the macros OVERRIDE and/or FINAL.

When combined with fix-its that introduce the C++11 override keyword, they become fatal, resulting in the modernize-use-override check being turned off to prevent the introduction of such errors.

This revision, allows the possibility for the replacement **override **to be a macro instead, Allowing the clang-tidy check to be run on  both pre and post C++11 code, and allowing fix-its to be applied.
