While writing tests for attribute flatten I wasn't 100% sure
from reading the manual if it would respect attribute noinline
or if it would override it. Turns out it's the former so
the attached patch mentions it in the manual. Unless there
are objections I will commit the change tomorrow.

Generally, inlining into a function is limited. For a function marked with
this attribute, every call inside this function is inlined, if possible.
