LOG: [OpenACC] enable 'deviceptr' for combined constructs.

This is another clause whose implementation is identical for combined
constructs as with compute constructs, so this adds tests and enables
it.

Added: 
    clang/test/SemaOpenACC/combined-construct-deviceptr-ast.cpp
    clang/test/SemaOpenACC/combined-construct-deviceptr-clause.c
    clang/test/SemaOpenACC/combined-construct-deviceptr-clause.cpp

Modified: 
    clang/lib/Sema/SemaOpenACC.cpp
    clang/test/AST/ast-print-openacc-combined-construct.cpp
    clang/test/SemaOpenACC/combined-construct-auto_seq_independent-clauses.c

Removed:
