This change copies over amd64-cloudabi64.c to aarch64-cloudabi.c and adjusts it to fetch the proper registers on aarch64. To reduce the amount of shared code, the errno conversion function is moved into a separate source file. Reviewed by: jhb, andrew Differential Revision: https://reviews.freebsd.org/D4023 END
