Summary:
This patch adds onTypeFormatting to clangd.
The trigger character is '}' and it works by scanning for the matching '{' and formatting the range in-between.
There are problems with ';' as a trigger character, the cursor position is before the `|`:
```
int main() {
int i;|
}
```
becomes:
```
int main() { int i;| }
```
which is not likely what the user intended.
Also formatting at semicolon in a non-properly closed scope puts the following tokens in the same unwrapped line, which doesn't reformat nicely.

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.

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 "./".

This is the first checker I wrote and I never did something with clang (only compiling programs). So whenever I missed conventions or did plain retarded stuff, feel free to point it out! I am willing to fix them and write a better checker.
I hope the patch does work, I never did this either. On a testapply in my repository it did, but I am pretty unconfident in my patching skills :)

Due to the way the preprocessor works nodes can be half in a macro or a
different file. This means checking the file name of the start location
of a Decl is not a correct way of checking if the entire Decl is in that
file. Remove that flawed assumption and replace it with a more effective
check: If the point we're looking for is *inside* of the begin and end
location of a Decl, look inside.
This should make clang-rename more reliable (for example macro'd namespaces
threw it off before, as seen in the test case) and maybe a little faster
by pruning off more stuff that the RecursiveASTVisitor doesn't have to
drill into.

struct der : base {
int field; // FIXES: int Field;
der() : der(42) {} // FIXES: Der() : Der(42) {}
der(int X) : base(), field(X) {} // FIXES: Der(int X) : Base(), field(X)

}
When changing from na::nb to x::y, "Base::Base" will be changed to "nx::ny::Base" and
"Base::" in "Base::Base" will be replaced with "nx::ny::Base" too, which causes
conflict. This conflict should've been detected when adding replacements but was hidden by `addOrMergeReplacement`. We now also detect conflict when adding replacements where conflict must not happen.
The namespace lookup is tricky here, we simply replace "Base::Base()" with "nx::ny::Base()" as a workaround, which compiles but not perfect.

Hello, i would like to suggest a fix for one of the checks in clang-tidy and i should hope this one is the correct mailing list.
The check is modernize-avoid-bind.
Consider the following:
void bar(int x, int y);
namespace N {
void bar(int x, int y);
}
void foo(){
auto Test = std::bind(N::bar,1,1);
}
clang-tidy’s modernize-avoid-bind check suggests writing:
void foo(){
auto Test =[] {return bar(1,1);};
}
instead of:
void foo(){
auto Test = [] {return N::bar(1,1);};
}
So clang-tidy has proposed an incorrect Fix.

This situation can be confusing to users because, in terms of source code
location, the use is above the move. This can make it look as if the warning
is a false positive, particularly if the loop is long but the use and move are
close together.
In cases like these, misc-use-after-move will now output an additional
