  Log Message:
  -----------
  [AARCH64][Neon] switch to using bitcasts in arm_neon.h where appropriate (#127043)

Currently arm_neon.h emits C-style casts to do vector type casts. This
relies on implicit conversion between vector types to be enabled, which
is currently deprecated behaviour and soon will disappear. To ensure
NEON code will keep working afterwards, this patch changes all this
vector type casts into bitcasts.
