Restoring random-field testing of fields which are not nullable arrays
Speed: Adding an ArrayEvent.get() speed test
Speed: Boosting number of performance test passes
Removing FieldType.fixedValues(), which appears to have been a testing artifact.  This also sped up the ArrayEventPerformanceTest just due to a sampling bias, by again testing fields that aren't nullable arrays
Speed: Don't deserialize values in find(); just skip them.  66% speed boost. (fixed speed regression in c4b12ae3e8d6369f88177dd62a7f3781532f59ab)
Speed: Don't deserialize a BitSet when we only want the cardinality.  38% speed boost.
Fixed an outdated comment
Speed: Avoiding the use of maps when checking attributes of FieldType
Speed: Improve getValueByteSize(), for a 15% improvement
Speed: Suppressing a log check in some of the most heavily-used code, for another 1-2% boost.
Speed: Cleaning up ArrayEvent.getValueByteSize()
Cleaned up whitespace in FieldType field declarations.
