No worries 😀

If we remove `ARM::AEK_SIMD` is removed, the target will not be able to process or generate NEON instructions. I have added it to all ArmV8-a (and beyond) architectures and the Cortex-R52 CPU. This should cover all the Cortex-A and Cortex-R targets that support it. As ArmV7-A has NEON as an optional feature, I have not added it here. The only thing I may have missed is if Arm V7-A CPU's Support NEON as a mandatory feature, I would need to check this.
