Inline pmap_activate() and pmap_deactivate() into the asm cpu_switchto routine, adding a check for the new pmap already being marked as active on the CPU.

Also, delete two other unused pcb members: pcb_usersp and pcb_flags. (Deleting pcb_usersp also keeps the pcb_savefpu member aligned properly.) Finally, delete the defines for the unimplemented AMD64_{GET,SET}_LDT sysarch() calls.
