Wait states are not properly being inserted after buffer_store for v_interp instructions. Add VALU to V_INTERP instructions so that the GCNHazardRecognizer can check and insert the appropriate wait states when needed. Differential Revision: https://reviews.llvm.org/D48772 Change-Id: Id540c9b074fc69b5c1de6b182276aa089c74aa64 llvm-svn: 336339
