Hi, Inspired by Jiong's recent work, here are some more missing intrinsics, and a smoke test for each of them.
This patch covers: vcvt_n_f64_s64 vcvt_n_f64_u64 vcvt_n_s64_f64 vcvt_n_u64_f64 vcvt_f64_s64 vrecpe_f64 vcvt_f64_u64 vrecps_f64 Tested on aarch64-none-elf, and on an internal testsuite for Neon intrinsics. Note that the new tests will ICE without the fixups in https://gcc.gnu.org/ml/gcc-patches/2016-06/msg00805.html OK?
