[PATCH] AArch64: Implement missing vrndns_f32 intrinsic

[Kyrylo Tkachov]

Hi all,

This patch implements the missing vrndns_f32 intrinsic. This operates on a 
scalar float32_t value.
It can be mapped down to a __builtin_aarch64_frintnsf builtin.

This patch does that.

Bootstrapped and tested on aarch64-none-linux-gnu.

Committing to trunk and to active branches later after testing.

Thanks,
Kyrill
