Ben Langmuir 6377199e2f [placeholder-expansion] Expand trailing closure in statements correctly ...

In addition to brace statements (previously handled), several other
statements allow a trailing closure (return, yield, throw). Also fix the
handling of statements nested within expressions for closures - both
single-expression bodies and brace statements.

This also fixes a particular regression caused by single-expression
function bodies where we would fail to expand to a trailing closure when
a function body only contained a single expression.
