There is expansion but in the case I strongly doubt we are trying
to stack reuse it for other vars, so maybe it is ok.

When NRV replaces a local variable with it also replaces
occurences in clobbers. This leads to being clobbered
before the return of it which is strictly invalid but harmless in
practice since there's no pass after NRV which would remove
