    GCN: Enable effective-target 'vect_long_long'
    
    ... as made apparent by a number of unexpectedly UNSUPPORTED test cases, which
    now all turn into PASS, with just one exception:
    
        PASS: gcc.dg/vect/vect-early-break_124-pr114403.c (test for excess errors)
        PASS: gcc.dg/vect/vect-early-break_124-pr114403.c execution test
        FAIL: gcc.dg/vect/vect-early-break_124-pr114403.c scan-tree-dump vect "LOOP VECTORIZED"
    
    ..., which needs to be looked into, separately.
    
            gcc/testsuite/
            * lib/target-supports.exp (check_effective_target_vect_long_long):
            Enable for GCN.
