[clang] LLVM ERROR: IO failure on output stream: Broken pipe with `--help` piped to `less(1)`

Consider the following:

```
$ clang --help | less
```
`clang` successfully pipes the output to `less`. If I either exit the pager or partially scroll the output and then exit, I get

```
LLVM ERROR: IO failure on output stream: Broken pipe
```

The only case in which this doesn't happen is if I scroll to the very bottom of the output and then exit the pager.
