Summary:
This would have caught a bug I wrote in an early version of D42049, where
an index user could overwrite data internal to the index because the Symbol is
not deep-const.
The YAML traits are now a bit more verbose, but separate concerns a bit more
nicely: ArenaPtr can be reused for other similarly-allocated objects, including
scalars etc.

Summary:
We now hide the static/dynamic split from the code completion, behind a
new implementation of the SymbolIndex interface. This will reduce the
complexity of the sema/index merging that needs to be done by
CodeComplete, at a fairly small cost in flexibility.

To stay fast, it avoids deserializing anything outside the current file, by
disabling the LoadExternal code completion option added in r322377, when the

Fixes bug 34701
When we encounter a namespace find the location of the left bracket.
Then if the text between the name and the left bracket contains a ':'
then it's a C++17 nested namespace.

Summary:
Use the YAML-format symbols (generated by the global-symbol-builder tool) to
do the global code completion.
It is **experimental** only , but it allows us to experience global code
completion on a relatively small project.
Tested with LLVM project.

Summary:
This patch removes hidden items from code completion.
Items can be hidden, e.g., by other items in the child scopes.
This patch addresses a particular problem of a duplicate completion
item for the class in the following example:
struct Adapter { void method(); };
void Adapter::method() {
Adapter^
}
We should probably investigate if there are other duplicates in
completion and remove them, possibly adding assertions that it never
happens.

A StringRef that goes out of scope was copied and used in a handler
running on a separate thread.
We didn't catch it because clangd does not use the async completion
API yet.

Summary:
We currently only collect external-linkage symbols in the collector,
which results in missing some typical symbols (like no-linkage type alias symbols).
This patch relaxes the constraint a bit to allow collecting more symbols.

Summary:
google-objc-global-variable-declaration currently triggers on
valid code like:
- (void)foo {
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{ /* ... */ });
}
The Google Objective-C style guide says:
http://google.github.io/styleguide/objcguide.html#common-variable-names
> File scope or global variables (as opposed to constants) declared
> outside the scope of a method or function should be rare, and should
> have the prefix g.
which is meant to insinuate that static variables inside a method or
function don't need a special name.

And also enable it by default to be consistent with e.g. modernize-use-using.
This helps e.g. when running this check on client code where the macro is
provided by the system, so there is no easy way to modify it.

Summary:
This improves a few things:
- the insert -> freeze -> read sequence is now enforced/communicated by the
type system
- SymbolSlab::const_iterator iterates over symbols, not over id-symbol pairs
- we avoid permanently storing a second copy of the IDs, and the
string map's hashtable
The slab size is now down to 21.8MB for the LLVM project.
Of this only 2.7MB is strings, the rest is #symbols * `sizeof(Symbol)`.
`sizeof(Symbol)` is currently 96, which seems too big - I think
SymbolInfo isn't efficiently packed. That's a topic for another patch!
Also added simple API to see the memory usage/#symbols of a slab, since
it seems likely we will continue to care about this.

Symbols are not self-contained - it's only safe to hand them out if you
guarantee the lifetime of the underlying data.
Before this lands, I'm going to measure the before/after memory usage of the

Summary:
The goal here is again to make it easier to read and write the tests.
I've extracted `parseTextMarker` from CodeCompleteTests into an `Annotations`
class, adding features to it:
- as well as points `^s` it allows ranges `[[...]]`
- multiple points and ranges are supported
- points and ranges may be named: `$name^` and `$name[[...]]`
These features are used for the xrefs tests. This also paves the way for
replacing the lit diagnostics.test with more readable unit tests, using named
ranges.
Alternative considered: `TestSelectionRange` in clang-refactor/TestSupport
Main problems were:
- delimiting the end of ranges is awkward, requiring counting
- comment syntax is long and at least as cryptic for most cases
- no separate syntax for point vs range, which keeps xrefs tests concise
- Still need to convert to Position everywhere
- Still need helpers for common case of expecting exactly one point/range
(I'll probably promote the extra `PrintTo`s from some of the core Protocol types
into `operator<<` in `Protocol.h` itself in a separate, prior patch...)
