I'm missing similar changes for NeonEmitter.cpp where this include would be added for arm_neon.h and where the types are removed from arm_neon.h so that we don't end up with duplicate typedefs.

Duplicate typedefs is not an issue when they are exactly the same (from C11 onward), but as I pointed out above, they are subtly different, which leads to issues.
