BulkInsert optimization for SplitRowStore
This change adds a struct which holds the calculations for insert
information for tuples coming from a value accessor and being inserted
into a splitrowstore tuple block. This greatly speeds up highly
unselective queries.

Removes duplicate code in bulkInsert
This refactor is meant to remove code complexity via removing duplicate
code. Prefer cleaner/more maintainable code over a slightly faster
algorithm.
