Optimize/cleanup BPIALL workaround
In the initial implementation of this workaround we used a dedicated
workaround context to save/restore state. This patch reduces the
footprint as no additional context is needed.
Additionally, this patch reduces the memory loads and stores by 20%,
reduces the instruction count and exploits static branch prediction to
optimize the SMC path.
