IMPALA-3838, IMPALA-4495: Codegen EvalRuntimeFilters() and fixes filter stats updates This change codegens HdfsParquetScanner::EvalRuntimeFilters() by unrolling its loop, codegen'ing the expression evaluation of the runtime filter and replacing some type information with constants in the hashing function of runtime filter to avoid branching at runtime. This change also fixes IMPALA-4495 by not counting a row as 'considered' in the filter stats before the filter arrives. This avoids unnecessarily marking a runtime filter as ineffective before it's even used. With this change, TPCDS-Q88 improves by 13-14%. primitive_broadcast_join_1 improves by 24%.
