By default, all traits in the OpenMP context selector have to match for
it to be acceptable. Though, we sometimes want a single property out of
multiple to match (=any) or no match at all (=none). We offer these
choices as extensions via
`implementation={extension(match_{all,any,none})}`
to the user. The choice will affect the entire context selector not only
the traits following the match property.
The first user will be D75788 <https://reviews.llvm.org/D75788>. There we can
replace
#pragma omp begin declare variant match(device={arch(nvptx64)})
#define __CUDA__
#include <__clang_cuda_cmath.h>
// TODO: Hack until we support an extension to the match clause that allows
"or".
#undef __CLANG_CUDA_CMATH_H__
#undef __CUDA__
#pragma omp end declare variant
#pragma omp begin declare variant match(device={arch(nvptx)})
#define __CUDA__
#include <__clang_cuda_cmath.h>
#undef __CUDA__
#pragma omp end declare variant
with the much simpler
#pragma omp begin declare variant match(device={arch(nvptx, nvptx64)},
implementation={extension(match_any)})
#define __CUDA__
#include <__clang_cuda_cmath.h>
#undef __CUDA__
#pragma omp end declare variant

and where `variant-func-id` is the name of a function variant that is either a

+Clang provides the following context selector extensions, used via `implementation={extension(EXTENSION)}`:
+
+ .. code-block:: none
+
+ match_all
+ match_any
+ match_none
+
+The match extensions change when the *entire* context selector is considered a
+match for an OpenMP context. The default is `all`, with `none` no trait in the
+selector is allowed to be in the OpenMP context, with `any` a single trait in
+both the selector and OpenMP context is sufficient. Only a single match
+extension trait is allowed per context selector.
