Add an option to suspend the src in a-b-bootblock.S, which puts the guest in S3 state after one round of writing to memory. The option is enabled by poking a 1 into the suspend_me word in the boot block prior to starting the src vm. Generate symbol offsets in a-b-bootblock.h so that the suspend_me offset is known. Generate the bootblock for each test, because suspend_me may differ for each.
