<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Fix ApplicativeDo regression #17835

A previous fix for #15344 made sure that monadic 'fail' is used properly
when translating ApplicativeDo. However, it didn't properly account
for when a 'fail' will be inserted which resulted in some programs
failing with a type error.
