Intrinsic `random_number` not recognised

[hiker]

The following code snippet from LFRic (taken from PSyclone's tests/psyad/tl2ad_test.py

real, dimension(npts) :: field
call random_number(field)

does not recognise random_number as an intrinsic. FParser returns it as:

 Call_Stmt(Name('random_number'), Actual_Arg_Spec_List(',', (Name('field'),)))

It should not be a Call_Stmt. I checked - it calls Call_Stmt.match, but not Intrinsic_Name.match.

date_and_time has the same issue. As has back_trace. I'll stop listing them :)
