compiler: Silence false warning for unmatched return in 'after' clause
Because 26940a8c0c lifted code in the 'after' clause of 'try' to
a new function, Dialyzer could produce false warnings for code such
as:
try
...
after
file:close(F)
end.
Mark the the call to the generated function as 'compiler_generated'
to silence the warning.
