Currently, clangd always completes `typename` as `typename qualifier::name`, I think the current behavior is not useful when the code completion is triggered in `template <>`. So I tweak it to `typename identifier`.

Summary:
Standardize the formatting of selector fragments to include the ':',
e.g. for `- (void)foobar:(int)foobar;`, report `{foobar:}` instead of
`{foobar}{:}`. This was normally the case except for a couple of places
where it was split.
This also improves integration with clangd since it relies upon the `:`
to identify ObjC selectors.
NOTE: It is possible to have selector fragments that are just `:` with
no text, we now handle this properly for the first fragment.

Summary:
Exempt ObjC from arrow/dot fixits since this has limited value for
Objective-C, where properties (referenced by dot syntax) are normally
backed by ivars (referenced by arrow syntax).
In addition, the current implementation doesn't properly mark
the fix it condition for Objective-C.
This was initially added in https://reviews.llvm.org/D41537
for C++ and then later C, don't believe the Objective-C changes

This is a code clean up of the PropertyAttributeKind and

into one. The changes are to many files across clang (and comments in LLVM) so

Summary:
The basic idea is to walk through the concept definition, looking for
t.foo() where t has the constrained type.
In this patch:
- nested types are recognized and offered after ::
- variable/function members are recognized and offered after the correct
dot/arrow/colon trigger
- member functions are recognized (anything directly called). parameter
types are presumed to be the argument types. parameters are unnamed.
- result types are available when a requirement has a type constraint.
These are printed as constraints, except same_as<T> which prints as T.
Not in this patch:
- support for merging/overloading when two locations describe the same member.
The last one wins, for any given name. This is probably important...
- support for nested template members (T::x<int>)
- support for completing members of (instantiations of) template template parameters

This is how it should've been and brings it more in line with
std::string_view. There should be no functional change here.
This is mostly mechanical from a custom clang-tidy check, with a lot of
manual fixups. It uncovers a lot of minor inefficiencies.
This doesn't actually modify StringRef yet, I'll do that in a follow-up.
Summary:
Printing policy was not propogated to functiondecls when creating a
completion string which resulted in canonical template parameters like
`foo<type-parameter-0-0>`. This patch propogates printing policy to those as
well.

Given the following code:

Triggering the completion at `^` would show `(lambda)` before this patch
and would show signature `(int a, double &b) const`, build a snippet etc

Currently, clang emits subprograms for declared functions when the
target debugger or DWARF standard is known to support entry values
(DW_OP_entry_value & the GNU equivalent).
Treat DW_AT_tail_call the same way to allow debuggers to follow cross-TU
tail calls.
Pre-patch debug session with a cross-TU tail call:
```
* frame #0: 0x0000000100000fa4 main`target at b.c:4:3 [opt]
frame #1: 0x0000000100000f99 main`main at a.c:8:10 [opt]
```
Post-patch (note that the tail-calling frame, "helper", is visible):
```
* frame #0: 0x0000000100000fa4 main`target at b.c:4:3 [opt]
frame #1: 0x0000000100000f80 main`helper [opt] [artificial]
frame #2: 0x0000000100000f99 main`main at a.c:8:10 [opt]

This was reverted in 5b9a072c because it attached declaration
subprograms to inlinable builtin calls, which interacted badly with the
MergeICmps pass. The fix is to not attach declarations to builtins.

Summary:
Completion can return multi-line patterns in some cases, e.g.
for (<#init#>; <#cond#>; <#inc#>) {
<#body#>
}
However, most patterns break the line only before closing brace,
resulting in code like:
namespace <#name#> { <#decls#>
}
While some (e.g. the 'for' example above) are breaking lines after the
opening brace too.
This change ensures all patterns consistently break after the opening
brace, this leads to nicer UX when using those in an actual editor.

this patch adds support for the explicit bool specifier.
Changes:
- The parsing for the explicit(bool) specifier was added in ParseDecl.cpp.
- The storage of the explicit specifier was changed. the explicit specifier was stored as a boolean value in the FunctionDeclBitfields and in the DeclSpec class. now it is stored as a PointerIntPair<Expr*, 2> with a flag and a potential expression in CXXConstructorDecl, CXXDeductionGuideDecl, CXXConversionDecl and in the DeclSpec class.
- Following the AST change, Serialization, ASTMatchers, ASTComparator and ASTPrinter were adapted.
- Template instantiation was adapted to instantiate the potential expressions of the explicit(bool) specifier When instantiating their associated declaration.
- The Add*Candidate functions were adapted, they now take a Boolean indicating if the context allowing explicit constructor or conversion function and this boolean is used to remove invalid overloads that required template instantiation to be detected.
- Test for Semantic and Serialization were added.
This patch is not yet complete. I still need to check that interaction with CTAD and deduction guides is correct. and add more tests for AST operations. But I wanted first feedback.
Perhaps this patch should be spited in smaller patches, but making each patch testable as a standalone may be tricky.
