    RISC-V: Enable vectorization for vect-early-break_124-pr114403.c
    
    Because "targetm.slow_unaligned_access" is set to true by default
    (aka -mtune=rocket) for RISC-V, it causes the __builtin_memcpy with
    8 bytes failed to folded into int64 assignment during ccp1.
    
    So adding "-mtune=generic-ooo" to the RISC-V target can vectorize
    vect-early-break_124-pr114403.c.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/vect-early-break_124-pr114403.c: Enable vectrization for RISC-V target.
