Sounds like a good set of instructions. LGTM
================
Comment at: llvm/lib/Target/AArch64/AArch64InstrInfo.cpp:4996-4998
+  // Opcodes MULv1i64 and MULv2i64 don't exist because corresponding
+  // `MUL <Vd>.1D, <Vn>.1D, <Vm>.1D` and `MUL <Vd>.2D, <Vn>.2D, <Vm>.2D`
+  // don't exist in the Advanced SIMD instruction set.
----------------
This could just say something like "there is no 64bit mul under neon".
