[clang][DeclPrinter] Pass Context into StmtPrinter whenever possible
ASTContext were only passed to the StmtPrinter in some places, while it
is always available in DeclPrinter. The context is used by StmtPrinter to better
print statements in some cases, like printing constants as written.

David Goldman 07c5a800dc Improve hover scopes for Objective-C code
- Instead of `AppDelegate::application:didFinishLaunchingWithOptions:` you
will now see `-[AppDelegate application:didFinishLaunchingWithOptions:]`

- Also include categories in the name when printing the scopes, e.g. `Class(Category)` and `-[Class(Category) method]`

Sam McCall b0615642f6 [clangd] Make our printing policies for Hover more consistent, especially tags
Different cases were using a bunch of different variants of the printing policy.
Each of these had something going for it, but the result was inconsistent.

Goals:
  - single printing policy used (almost) everywhere
  - avoid unidiomatic tags like `class vector<class X>`
  - be informative and easy to understand

For tags, the solution I wound up with is: we print only the outer tag and only
in the simplest cases where this elaboration won't cause confusion.

For example:
 - class X
 - enum Foo
 - vector<int>
 - X*

This seems to strike a nice balance of providing plenty of info/context in common
cases while never being confusing.

Quentin Chateau c46c7c9bcf [clangd] Smarter hover on auto and decltype
Only show the keyword as the hover "Name".

Show whether the type is deduced or undeduced as
the hover "Documentation".

Show the deduced type (if any) as the "Definition".

Don't show any hover information for:
- the "auto" word of "decltype(auto)"
- "auto" in lambda parameters
- "auto" in template arguments

---------------

This diff is a suggestion based on what @sammccall  suggested in https://reviews.llvm.org/D92977 about hover on "auto". It somehow "hacks" onto the "Documentation" and "Definition" fields of `HoverInfo`. It sure looks good on VSCode, let me know if this seem acceptable to you.

Haojian Wu fcf0764998 [AST] Fix an assertion violation in FieldDecl::getParent.
Summary:
FieldDecl::getParent assumes that the FiledDecl::getDeclContext returns a
RecordDecl, this is true for C/C++, but not for ObjCIvarDecl:

The Decls hierarchy is like following

FieldDecl <-- ObjCIvarDecl

DeclContext <-- ObjCContainerDecl <-- ObjCInterfaceDecl
         ^
         |----- TagDecl <-- RecordDecl

calling getParent() on ObjCIvarDecl will:
1. invoke getDeclContext(), which returns a DeclContext*, which points to an ObjCInterfaceDecl;
2. then downcast the "DeclContext" pointer to a RecordDecl*, and we will hit
the "is_a<RecordDecl>" assertion in llvm::cast (undefined behavior
in release build without assertion enabled);

Sam McCall d3260bf5b2 [clangd] Errors in TestTU cause test failures unless suppressed with error-ok.
Summary:
The historic behavior of TestTU is to gather diagnostics and otherwise ignore
them. So if a test has a syntax error, and doesn't assert diagnostics, it
silently misbehaves.
This can be annoying when developing tests, as evidenced by various tests
gaining "assert no diagnostics" where that's not really the point of the test.

This patch aims to make that default behavior. For the first error
(not warning), TestTU will call ADD_FAILURE().

This can be suppressed with a comment containing "error-ok". For now that will
suppress any errors in the TU. We can make this stricter later -verify style.
(-verify itself is hard to reuse because of DiagnosticConsumer interfaces...)
A magic-comment was chosen over a TestTU option because of table-driven tests.

In addition to the behavior change, this patch:
  - adds //error-ok where we're knowingly testing invalid code
    (e.g. for diagnostics, crash-resilience, or token-level tests)
  - fixes a bunch of errors in the checked-in tests, mostly trivial (missing ;)
  - removes a bunch of now-redundant instances of "assert no diagnostics"
