aarch64: Reimplement vrshrn* intrinsics using builtins
This patch moves the vrshrn* intrinsics to builtins away from inline
asm.
It's a bit of code, but it's very similar to the recent vsrhn*
reimplementation except that we use an unspec rather than standard RTL
codes for the functionality.
gcc/ChangeLog:
* config/aarch64/aarch64-simd-builtins.def (rshrn, rshrn2):
Define builtins.
* config/aarch64/aarch64-simd.md (aarch64_rshrn<mode>_insn_le):
Define.
