Kazu Hirata 5891420e68 [clang] Use std::nullopt instead of None (NFC)
This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated.  The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.

This is part of an effort to migrate from llvm::Optional to
std::optional:

Saleem Abdulrasool b78d5380da parse: process GNU and standard attributes on top-level decls
We would previously reject valid input where GNU attributes preceded the
standard attributes on top-level declarations. A previous attribute
handling change had begun rejecting this whilst GCC does honour this
layout. In practice, this breaks use of `extern "C"` attributed
functions which use both standard and GNU attributes as experienced by
the Swift runtime.

Objective-C deserves an honourable mention for requiring some additional
special casing. Because attributes on declarations and definitions
differ in semantics, we need to replicate some of the logic for
detecting attributes to declarations to which they appertain cannot be
attributed. This should match the existing case for the application of
GNU attributes to interfaces, protocols, and implementations.

Take the opportunity to split out the tooling tests into two cases: ones
which process macros and ones which do not.

Special thanks to Aaron Ballman for the many hints and extensive rubber
ducking that was involved in identifying the various places where we
accidentally dropped attributes.

Mike Rice 129904d504 [OpenMP][NFC] Use OMPInteropInfo in the OMPDeclareVariantAttr attribute
In preparation for allowing the prefer_type list in the append_args clause,
use the OMPInteropInfo in the attribute for 'declare variant'.

This requires adding a new Argument kind to the attribute code. This change
adds a specific attribute to pass an array of OMPInteropInfo. It implements
new tablegen needed to handle the interop-type part of the structure. When
prefer_type is added, more work will be needed to dump, instantiate, and
serialize the PreferTypes field in OMPInteropInfo.

Mike Rice 89167e3c5b [OpenMP][NFC] Refactor code for interop parts of 'init' and 'append_args' clauses
The 'init' clause allows an interop-modifier of prefer_type(list) and
and interop-types 'target' and 'targetsync'.

The 'append_args' clause uses an append-op that also includes
interop-types ('target' and 'targetsync') and will allow
a prefer_type list in the next OpenMP version.

This change adds a helper struct OMPInteropInfo and uses it in the parsing
of both the 'init' and 'append_args' clauses.

One OMPInteropInfo object represents the info in a single 'init' clause.
Since 'append_args' allows a variable number of interop items it will
require an array of OMPInteropInfo objects once that is supported.

Martin Boehme 8c7b64b5ae [clang] Reject non-declaration C++11 attributes on declarations
For backwards compatiblity, we emit only a warning instead of an error if the
attribute is one of the existing type attributes that we have historically
allowed to "slide" to the `DeclSpec` just as if it had been specified in GNU
syntax. (We will call these "legacy type attributes" below.)

The high-level changes that achieve this are:

- We introduce a new field `Declarator::DeclarationAttrs` (with appropriate
  accessors) to store C++11 attributes occurring in the attribute-specifier-seq
  at the beginning of a simple-declaration (and other similar declarations).
  Previously, these attributes were placed on the `DeclSpec`, which made it
  impossible to reconstruct later on whether the attributes had in fact been
  placed on the decl-specifier-seq or ahead of the declaration.

- In the parser, we propgate declaration attributes and decl-specifier-seq
  attributes separately until we can place them in
  `Declarator::DeclarationAttrs` or `DeclSpec::Attrs`, respectively.

- In `ProcessDeclAttributes()`, in addition to processing declarator attributes,
  we now also process the attributes from `Declarator::DeclarationAttrs` (except
  if they are legacy type attributes).

- In `ConvertDeclSpecToType()`, in addition to processing `DeclSpec` attributes,
  we also process any legacy type attributes that occur in
  `Declarator::DeclarationAttrs` (and emit a warning).

- We make `ProcessDeclAttribute` emit an error if it sees any non-declaration
  attributes in C++11 syntax, except in the following cases:
  - If it is being called for attributes on a `DeclSpec` or `DeclaratorChunk`
  - If the attribute is a legacy type attribute (in which case we only emit
    a warning)

The standard justifies treating attributes at the beginning of a
simple-declaration and attributes after a declarator-id the same. Here are some
relevant parts of the standard:

- The attribute-specifier-seq at the beginning of a simple-declaration
  "appertains to each of the entities declared by the declarators of the
  init-declarator-list" (https://eel.is/c++draft/dcl.dcl#dcl.pre-3)

- "In the declaration for an entity, attributes appertaining to that entity can
  appear at the start of the declaration and after the declarator-id for that
  declaration." (https://eel.is/c++draft/dcl.dcl#dcl.pre-note-2)

- "The optional attribute-specifier-seq following a declarator-id appertains to
  the entity that is declared."
  (https://eel.is/c++draft/dcl.dcl#dcl.meaning.general-1)

The standard contains similar wording to that for a simple-declaration in other
similar types of declarations, for example:

- "The optional attribute-specifier-seq in a parameter-declaration appertains to
  the parameter." (https://eel.is/c++draft/dcl.fct#3)

- "The optional attribute-specifier-seq in an exception-declaration appertains
  to the parameter of the catch clause" (https://eel.is/c++draft/except.pre#1)

The new behavior is tested both on the newly added type attribute
`annotate_type`, for which we emit errors, and for the legacy type attribute
`address_space` (chosen somewhat randomly from the various legacy type
attributes), for which we emit warnings.
