Hello,

This patch supports the following MVE ACLE store intrinsics.

vstrbq_scatter_offset_s8, vstrbq_scatter_offset_s32, vstrbq_scatter_offset_s16,
vstrbq_scatter_offset_u8, vstrbq_scatter_offset_u32, vstrbq_scatter_offset_u16,
vstrbq_s8, vstrbq_s32, vstrbq_s16, vstrbq_u8, vstrbq_u32, vstrbq_u16,
vstrwq_scatter_base_s32, vstrwq_scatter_base_u32.

Please refer to M-profile Vector Extension (MVE) intrinsics [1]  for more details.
[1]  https://developer.arm.com/architectures/instruction-sets/simd-isas/helium/mve-intrinsics

Regression tested on arm-none-eabi and found no regressions.

Ok for trunk?

Thanks,
Srinath.
