/*
Aggregates result types from the array of items.
SYNOPSIS:
agg_cmp_type()
type [out] the aggregated type
items array of items to aggregate the type from
nitems number of items in the array
DESCRIPTION
This function aggregates result types from the array of items. Found type
supposed to be used later for comparison of values of these items.
Aggregation itself is performed by the item_cmp_type() function.
NOTES
Aggregation rules:
If all items are constants the type will be aggregated from all items.
If there are some non-constant items then only types of non-constant
items will be used for aggregation.
