    [TRAFODION-1920] suppress SQL error during HIVE_SCAN when conv error

    A new PR for JIRA 1920. When read from HDFS in HIVE_SCAN and encounter invalid data, continue
and set the offending data to null.
    Latest implementation details:
    In code gen of HIVE_SCAN, if the CQD HIVE_SCAN_SPECIAL_MODE is set to '2'. Generate a
CAST function setting a special flag. In that CAST codegen, it will set runtime flag based
on the special flag. This will create a special ex_conv_clause.
    Codegen also disable pCode in this mode.
    At runtime, ex_conv_caluse::eval() will move null into target if convDoIt() failed. And
