This change compute the real number of true and false statistics information for boolean columns. Before this, impala used to set numTrues and numFalses to hardcoded -1 to indicate that its statistics is missing. Test Done: Append the numTrue and numFalse test for all the statistics-related test cases including the non-incremental, incremental and other test cases.
