[CodeCompletion] Provide member completions for dependent expressions whose
type is a TemplateSpecializationType or InjectedClassNameType

Fixes PR30847. Partially fixes PR20973 (first position only).

PR17614 is still not working, its expression has the dependent
builtin type. We'll have to teach the completion engine how to "resolve"
dependent expressions to fix it.

P0091R3: Implement basic parsing support for C++17 deduction-guides.

We model deduction-guides as functions with a new kind of name that identifies
the template whose deduction they guide; the bulk of this patch is adding the
new name kind. This gives us a clean way to attach an extensible list of guides
to a class template in a way that doesn't require any special handling in AST
files etc (and we're going to need these functions we come to performing
deduction).

[CodeCompletion] Block property setters: Use dynamic priority heuristic

Now when completing blocks properties that return void the block call completion
result shows up before the setter, otherwise the setter completion shows up
before the block call completion. We normally want to use the result of the
block call, so one typically wouldn't call a block that returns a non-void type
in a standalone statement.

Remove no-op checks for a null CodeCompleter. We have already
dereferenced the pointer at this point, and these routines are
exclusively called after the parser encounters a code completion token.
Other code completion routines called at that point do not check for
null either, so this is clearly the current invariant expected in the
code.

This fixes another PVS-Studio found issue.

[CodeCompletion] Add a block property setter completion result

This commit changes code completion results for Objective-C block properties:
clang now suggests an additional completion result that displays the block
property together with '=' and the block literal placeholder for the appropriate
readwrite block properties.

This commit uses a simple heuristic to determine when it's appropriate to
suggest a setter completion for block properties: the additional block setter
completion is provided iff the member access that's being completed is a
standalone statement.
