[PATCH] Invalidate argument slots for const/pure calls

Authentication-results: sourceware.org; auth=none

The attached patch fixes PR middle-end/71712.  We need to invalidate the argument slots in
const/pure calls as they are owned by the callee.  The caller can't assume they are preserved
across the call.  Fix is similar to that for PR71532.

Tested on hppa-unknown-linux-gnu.

Okay for trunk?

Dave
