In passing, split it up into three values (no explicit functions /
explicit conversion functions only / any explicit functions) in
preparation for using that in a future change.
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.
If local allocator was declared and used in the allocate clause, it was
not captured in inner region. It leads to a compiler crash, need to
capture the allocator declarator.
Target regions have implicit outer region which may erroneously capture
some globals when it should not. It may lead to a compiler crash at the
compile time.
declare simd.
According to the standard, a list-item that appears in a linear clause without the ref modifier must be of integral or pointer type, or must be a reference to an integral or pointer type. Added check that this restriction is applied only to non-ref items.
The OpenMP specification disallows having zero-length array
sections in the depend clause (OpenMP 5.0 2.17.11).

Summary: `getListOfPossibleValues()` formatted incorrectly when there is only one value, emitting something like `expected 'conditional' or in OpenMP clause 'lastprivate'`.

This removes the OpenMPProcBindClauseKind enum in favor of
llvm::omp::ProcBindKind which lives in OpenMPConstants.h and was
introduced in D70109.
No change in behavior is expected.

Summary:
Basic codegen for the declarations marked as nontemporal. Also, if the
base declaration in the member expression is marked as nontemporal,
lvalue for member decl access inherits nonteporal flag from the base
lvalue.

Summary:
The new OpenMPConstants.h is a location for all OpenMP related constants
(and helpers) to live.
This patch moves the directives there (the enum OpenMPDirectiveKind) and
rewires Clang to use the new location.
Initially part of D69785.

A trivially copyable type provides a trivial copy constructor and a trivial
copy assignment operator. This is enough for the runtime to memcpy the data
to the device. Additionally there must be no virtual functions or virtual
base classes and the destructor is guaranteed to be trivial, ie performs
no action.
The runtime does not require trivial default constructors because on alloc
the memory is undefined. Thus, weaken the warning to be only issued if the
mapped type is not trivially copyable.

simd-based directives.
According to OpenMP 5.0 standard, ordered simd, atomic and simd
directives are allowed as nested directives in the simd-based
directives.
If the context selector score was not specified, its value must be set
to 0. Simplify the processing of unspecified scores + save memory in
attribute representation.
