Change subject: IMPALA-3245 / IMPALA-3305: Fix crash with global filters when NUM_NODES=1

Patch Set 2:


One more bug-fix needed - computeHasLocalTarget() wasn't being called if the join was partitioned.
This was probably because there were so many return paths from createHashJoinFragment() that
it seemed a good idea to save the LOC required to add that logic after the fragment was completed

To address that, I moved the partition fragment-creation logic into its own method (since
createHJF() was ~200 lines already), so now we only have to compute filter locality in one
File be/src/runtime/coordinator.h:

Line 414:   /// Sets `filter_routing_table_complete_` and prints the table to the profile
and log.
> nit: don't we typically prefer single quotes over backticks?
File fe/src/main/java/com/cloudera/impala/planner/

Line 109:     // If true, the filter is produced by a broadcast join and is applied on a scan
> Maybe slightly rephrase to say
