    testsuite/116397 - avoid looking for "VEC_PERM_EXPR"
    
    With SLP this token appears a lot, when looking for what gets code
    generated instead look for " = VEC_PERM_EXPR"
    
            PR testsuite/116397
            * gcc.dg/vect/slp-reduc-3.c: Look for " = VEC_PERM_EXPR"
            instead of "VEC_PERM_EXPR".
