IMPALA-12744: Support for regr_count() aggregate/analytic function

regr_count() function can be used both as aggregate and
analytic function and is commonly used in regression analysis.

regr_count(y, x) returns an integer that is the number of non-null
number pairs. It indicates how many observations are included in the
analysis.

Testing:
The functions are extensively tested and cross-checked with Hive.
The tests can be found in aggregation.test.
