    x86_64: Prepare for x2apic support.
    
    - Use macro to access and modify LAPIC registers.
    - Use function pointers for hot LAPIC operation, i.e. IPI and timer.
    - Refactor the related code a bit.
    
    Global variable 'lapic' is renamed to 'lapic_mem' to ease code search.
    
    Based on work by ivadasz at .
