ARM64: Fix for handling GC register for call site

This fixes https://github.com/dotnet/coreclr/issues/2731.
Looking at GC heap corruption, JIT incorrectly reports the live range of
GC references so GC swept the live objects.
The issue was when JIT emits call instruction, GC live register is not
processed at all, which JIT treated them as dead.
The fix is to implement this missing part for ARM64.
