-    AMDGPU: Make various vector undefs legal
-
-    Surprisingly these were getting legalized to something
-    zero initialized.
-
-    This fixes an infinite loop when combining some vector types.
-    Also fixes zero initializing some undef values.
-
-    SimplifyDemandedVectorElts / SimplifyDemandedBits are not checking
-    for the legality of the output undefs they are replacing unused
-    operations with. This resulted in turning vectors into undefs
-    that were later re-legalized back into zero vectors.
-
-    (cherry picked from commit 7a84624079a2656c684bed6100708544500c5a32)
+    Bump version to 15.0.5
