Auto merge of #21894 - dotdash:assume_rc, r=alexcrichton
This is half of what @Aatch implemented in #21418. The non-null assumption is later canonicalized to !nonnull metadata and doesn't cause any slowdowns (in fact the build is slightly faster with this change). I left out the other half of #21418 because that still causes a ~16% increase in compile times (30m -> 35m).
