This is a little indiscriminate, I'd very much prefer that we do this
per-target. As-is, we'll end up building every target that includes this file
with WPO, and WPO consumes CPU and memory superlinear to the input size.
You really don't want to slow down the official build by WPO-optimizing your
test and misc executables.
