When including <ostream>, the register_callback macro of the OMPT callback.h
clashes with a function defined in ostream. This patch renames the macro
and includes ompt into the macro name.

This patch adds the new zero_bits operation and upstrams other changes
including the following:

  - update tablegen syntax to newer forms
  - update memory effects annotations
  - update documentation [NFC]
  - other NFC, such as whitespace and formatting

If a check-suffix is only required for a CHECK-FIXES or CHECK-MESSAGES. check_clang_tidy will pass the prefixes CHECK-FIXES<...> and CHECK-MESSAGES<...> to FileCheck.
This will result in a FileCheck failing because of an unused prefix.

This addresses the problem by not passing unused prefixes. Its also possible to fix this be passing `--allow-unused-prefixes` flag to FileCheck, but seeing as we have already done the legwork in the script to see its unused, this fix seems the better way to go.

The current API for printing errors/warnings/messages from LLDB commands
sometimes adds newlines behind the messages for the caller. However, this
happens unconditionally so when the caller already specified a trailing newline
in the error message (or is trying to print a generated error message that ends
in a newline), LLDB ends up printing both the automatically added newline and
the one that was in the error message string. This leads to all the randomly
appearing new lines in error such as:

```
(lldb) command a
error: 'command alias' requires at least two arguments
(lldb) apropos a b
error: 'apropos' must be called with exactly one argument.

(lldb) why is there an empty line behind the second error?
```

This code adds a check that only appends the new line if the passed message
doesn't already contain a trailing new line.

Also removes the AppendRawWarning which had only one caller and doesn't serve
any purpose now.

`ValueObject.h` contains the `ValueObject::ValueObjectManager` type which is
just a typedef for the ClusterManager that takes care of the whole ValueObject
memory management. However, there is also `ValueObjectManager` defined in the
same header which is only used in the curses UI implementation and consists
mostly of dead and completely untested code.

This code been around since a while (it was added in 2016 as
8369b28d), so I think we shouldn't just revert
the whole patch.

Instead this patch just moves the class to its own header that it isn't just
hiding in the ValueObject header and renames it to `ValueObjectUpdater` that it
at least has a unique name (which I hope also slightly better reflects the
purpose of this class). I also deleted all the dead code branches and functions.

Differential Revision: https://reviews.llvm.org/D97203

LLDB tracks where any imported `clang::Decl` originally came from via a simple
map from 'imported decl' to 'original decl'. That information is used to later
complete parts of the Decl when more information is requested about a certain
Decl (e.g., via the ExternalASTSource interface from Clang).

When finding the 'original decl' for a given decl, the ASTImporterDelegate
essentially just recursively follows the previously mentioned map from
'imported' to 'original decl' until it can find any further 'original decl'. The
final found decl is then the one that will be imported. The recursion is
necessary as in LLDB we don't just import decls from one ASTContext to another,
but also from one ASTContext to another via a (potentially temporary)
ASTContext. For example, the expression parser creates a temporary ASTContext
for parsing the current expression.

The problem with the recursion is however that if we somehow get a cycle into
our mapping, then the ASTImporterDelegate will just infinite recurse. As the
infinite recursion usually happens after the cycle was already created in a code
path such as completing a type, the crash backtraces we get for these bugs are
not very useful. However having the backtrace where the faulty map entry is
created usually makes the code trivial to fix (as there should be some rogue
CopyType call or something similar nearby. See for example D96366).

This patch tries to make these issues easier to track down by putting a bunch of
sanity asserts in the code that fills out the map. All the asserts are just
checking that there is no direct cycle (ASTContext maps to itself) when updating
the origin tracking map.

The assert in the ASTImportDelegate constructor is an `lldbassert` (which also
is getting checked in release builds with disabled asserts) as the code path
there is pretty cold and we can reliably detect a rogue CopyType call from
there.

I also had to update some code in
`ClangASTImporter::ASTImporterDelegate::Imported`. This code already had a
safety check for creating a cycle in the origin tracking map, but it still
constructed an ASTImporter while checking for the cycle (by requesting a
delegate via `GetDelegate` and passing two identical ASTContexts which looks
like a rogue CopyType call to the checks).
