sh: initial stack protector support.
This implements basic -fstack-protector support, based on the early ARM version in c743f38013aeff58ef6252601e397b5ba281c633. The SMP case is limited to the initial canary value, while the UP case handles per-task granularity (limited to 32-bit sh until a new enough sh64 compiler manifests itself).
