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.
