Alexey Bataev 303657a6c6 [OPENMP50]Multiple vendors in vendor context must be treated as logical 
and of vendors, not or.

If several vendors are provided in the same vendor context trait, the
context shall match only if all vendors are matching, not one of them.
This is per OpenMP 5.0, 2.3.3 Matching and Scoring Context Selectors,
all selectors in the construct, device, and implementation sets of the
context selector appear in the corresponding trait set of the OpenMP
context.
