FWIW, this is because you broke the encoding of an instruction in your patch.  This is incorrect:

+def MOVNTDQ_64mr : PSI<0xE7, MRMDestMem, (outs), (ins f128mem:$dst, VR128:$src),
+                    "movntdq\t{$src, $dst|$dst, $src}",
+                    [(alignednontemporalstore (v2f64 VR128:$src), addr:$dst)]>;

Please don't check in patches when you know that they break testcases.
