This change adds the missing switch statement in CodegenReadScalar() for AVRO_DECIMAL so that we will also codegen if an avro table contains AVRO_DECIMAL. With this change, the following query improves by 37.5%, going from 8s to 5s: select count(distinct l_linenumber), avg(l_extendedprice), max(l_discount), min(l_tax) from tpch15_avro.lineitem; This change also un-inlines BitUtil::ByteSwap() as the third argument 'len' is not compilation constant for all call sites.
