[NEON] Support VST1xN intrinsics in AArch32 mode (LLVM part)

[kosarev]

Summary

We currently support them only in AArch64. The NEON Reference, however, says they are 'ARMv7, ARMv8' intrinsics.

[kosarev]

Ping.

[SjoerdMeijer]

Agreed: supported architectures are v7/A32/A64.
Thanks for fixing this.
