David BlaikieandJon Ross-Perkins e6c1f0630a Add a newline after diagnostic output when testing (#4818) 
This removes some churn when adding new diagnostic cases to test files
(where previous to this change the newly added newline would cause the
previous diagnostic CHECKs to be updated including changes to the line
number because the CHECK for the blank line meant an extra line between
CHECK and source line).

A few alternatives discussed here:
