Thomas Tauber-Marshall 343bdad866 IMPALA-3210: last/first_value() support for IGNORE NULLS 
Added support for the 'ignore nulls' keyword to the last_value and
first_value analytic functions, eg. 'last_value(col ignore nulls)',
which would return the last value from the window that is not null,
or null if all of the values in the window are null.

We handle 'ignore nulls' in the FE in the same way that we handle
'distinct' - by adding isIgnoreNulls as a field in FunctionParams.

To avoid affecting performance when 'ignore nulls' is not used, and
to avoid having to special case 'ignore nulls' on the backend, this
patch adds 'last_value_ignore_nulls' and 'first_value_ignore_nulls'
builtin analytic functions that wrap 'last_value' and 'first_value'
respectively.
