AMDGPU: Remove kills following clusters of memory instruction

In a future commit, soft clauses will be hinted with kill instructions
rather than forced together with bundles. Look for kills that look
like this, and erase them. I'm not sure if the check for specific uses
is worthwhile, or if it would be better to just unconditionally erase
kills.

This reduces test churn in a future patch.
