<pre>Sample code:
```
function t() {
if (true) return
const v = 42
}
```
clang-format result:
```
function t() {
if (true)
return const v = 42
}
```
which is incorrect in grammar.
According to ECMA262 12.9.1 [1], a semicolon should be automatically inserted
after "return" for the code sample (also, there's is an example in 12.9.2 like
this). After manually inserting a semicolon after "return", the clang-format
returns the correct formatting result.
