Auto merge of #345 - fitzgen:use-feature-for-dangling-item-asserts, r=emilio

Use a feature to control dangling item assertions

These checks are expensive enough that we only want to do them when hacking on
bindgen itself, not anytime someone does a debug build of something that depends
on bindgen.
