IMPALA-5008: Fix reading stats for TINYINT and SMALLINT TINYINT and SMALLINT types use 1 and 2 byte slots respectively. However, statistics for the corresponding INT_8 and INT_16 Parquet types are encoded using 4 bytes. When reading back we were missing a conversion to the smaller types, thus overwriting the memory behind them. This was caught by the address sanitizer. The fix is to perform the necessary conversion.
