Xcode uses `#pragma mark -` to draw a divider in the outline view
and `#pragma mark Note` to add `Note` in the outline view. For more
information, see https://nshipster.com/pragma/.
Since the LSP spec doesn't contain dividers for the symbol outline,
instead we treat `#pragma mark -` as a group with children - the
decls that come after it, implicitly terminating when the symbol's
parent ends.
The following code:
```
@implementation MyClass
- (id)init {}
- (int)foo;
@end
```
Would give an outline like
```
MyClass
> Overrides
> init
> Public Accessors
> foo
```

That macro was being defined but not used anywhere in libc++, so it
must be safe to remove it.
As a fly-by fix, also remove mentions of this macro in other places
in LLVM, to make sure they were not depending on the value defined in
libc++.

SourceLocation of macros change when a header file is included above it. This is not checked when creating a PreamblePatch, resulting in reusing previously built preamble with an incorrect source location for the macro in the example test case.
This patch stores the SourceLocation in the struct TextualPPDirective so that it gets checked when comparing old vs new preambles.
Also creates a preamble patch for code completion parsing so that clangd does not crash when following the example test case with a large file.

Even though they're implemented via typedefs, we typically
want to treat them like keywords.
We could add hover information / xrefs, but it's very unlikely

Rename methods to clearly signal when they only deal with ASCII,
simplify the parsing of identifier, and use start/continue instead of
head/body for consistency with Unicode terminology.
This helps improve the syntax highlighting for Objective-C code,
although it currently doesn't work well in VS Code with
methods/properties/ivars since we don't currently include the proper
decl context (e.g. class).

I discovered this quirk when working on some DWARF - AST printing prints
type template parameters fully qualified, but printed template template
parameters the way they were written syntactically, or wholely
unqualified - instead, we should print them consistently with the way we
print type template parameters: fully qualified.
The one place this got weird was for partial specializations like in
ast-print-temp-class.cpp - hence the need for checking for
TemplateNameDependenceScope::DependentInstantiation template template
parameters. (not 100% sure that's the right solution to that, though -
open to ideas)

This is the first patch in an ongoing attempt of Include Cleaner: unused/missing
headere diagnostics, an IWYU-like functionality implementation for clangd. The
work is split into (mostly) distinct and parallelizable pieces:
- Finding all referenced locations (this patch).
- Finding all referenced locations of macros.
- Building IncludeGraph and marking headers as unused, used and directly used.
- Making use of the introduced library and add an option to use in clangd.

* Adding support for standard library headers (possibly through mapping
genfiles).

Only the bare name is completed, with no args.
For args to be useful we need arg names. These *are* in the tablegen but
not currently emitted in usable form, so left this as future work.
C++11, C2x, GNU, declspec, MS syntax is supported, with the appropriate
spellings of attributes suggested.
`#pragma clang attribute` is supported but not terribly useful as we
only reach completion if parens are balanced (i.e. the line is not truncated)
There's no filtering of which attributes might make sense in this
grammatical context (e.g. attached to a function). In code-completion context
this is hard to do, and will only work in few cases :-(
There's also no filtering by langopts: this is because currently the
only way of checking is to try to produce diagnostics, which requires a
valid ParsedAttr which is hard to get.
This should be fairly simple to fix but requires some tablegen changes
to expose the logic without the side-effect.

These aren't terribly common, but we currently mishandle them badly.
Not only do we not recogize the attributes themselves, but we often end up
selecting some node other than the parent (because source ranges aren't accurate
in the presence of attributes).

This patch strips all the arch options in case of multiple ones. As it
results in multiple compiler jobs, which clangd cannot handle.
It doesn't pick any over the others as it is unclear which one the user wants
and defaulting to host architecture seems less surprising. Users also have the
ability to explicitly specify the architecture they want via clangd config
files.

It is not great to list diag ids by hand, but I don't see any other
solution unless diagnostics are annotated with these explicitly, which is a
bigger change in clang and I am not sure if would be worth it.
Diagnostics handled by this patch is by no means exhaustive, there might be
other checks that don't mention "unused"/"deprecated" in their names. But it
feels like this should be enough to catch common diagnostics and can be extended
over time.
