Why are we not also using bit cast for tuple types in line 1377. When I looks
at arm_neon.h I can see this:
__ret = (uint8x16_t) __builtin_neon_vqtbx4q_v(__builtin_bit_cast(int8x16_t,
__p0), (int8x16_t)__p1.val[0], (int8x16_t)__p1.val[1], (int8x16_t)__p1.val[2],
(int8x16_t)__p1.val[3]
Only p0 is using bit cast, while the others still use cast.
