ARM: Emit normal IR for vaddhn/vsubhn NEON intrinsics
These operations "vector add high-half narrow" actually correspond to the
sequence:
%sum = add <4 x i32> %lhs, %rhs
%high = lshr <4 x i32> %sum, <i32 16, i32 16, i32 16, i32 16>
%res = trunc <4 x i32> %high to <4 x i16>
Now that LLVM can spot this, Clang should emit the corresponding LLVM IR.
