[PATCH] Implement aarch64 neon instruction class AdvSIMD (by element) - Clang

In the clang changes, some of the intrinsics name carry a 'q' at the end of the base function name ( e..g., vmla_laneq). As a consequence you have to define a Q and non-Q version of the intrinsic declaration.
Do you think it is better to add the 'q' using a size modifier like "128b but mangling 'q' at the end of base neon function name". I did something like that for the scalar by element intrinsics where I need to generate names like 'vmulxd_laneq_f64'.
But in your case it seems you need 'q' both before the first '_' and at the end of the base neon function name. Is that the reason you did not use a type modifier? You would need yet another size modifier like '128b but mangling 'q' at both places".
It would be best if we agree on a common way to handle the 'q' at the end of base neon function name.
