    Fix comment for operand_compare::operand_equal_p.
    
    The OEP_* enums were moved to tree-core.h in
    r0-124973-g5e351e960763 but the comment was correct
    when it was added added to fold-const.h in
    r10-4231-g7f4a8ee03d40. This fixes the reference
    to the OEP_* enum to reference tree-core.
    
    Committed as obvious after a bootstrap/test on x86_64-linux.
    
    gcc/ChangeLog:
    
            * fold-const.h (operand_compare::operand_equal_p):
            Fix comment about OEP_* flags.
